The Form I-129F package that USCIS actually requires is shorter than most people expect. The agency’s own initial-evidence list runs to seven categories: proof you are a U.S. citizen, proof any prior marriages legally ended, one passport-style photo of each of you, evidence of a legal name change if either name has changed, an International Marriage Broker Regulation Act (IMBRA) waiver if you need one, and, for a K-1, evidence that you and your fiance(e) intend to marry within 90 days and met in person within the two years before you filed. The fee is $675, the current form edition is 01/20/25, and the whole package goes to one address: the USCIS Dallas lockbox.
This checklist covers the petition stage only. That is the stage where you, the U.S. citizen, mail a paper petition to USCIS asking it to classify your fiance(e) as a K-1 nonimmigrant. It is not the consular stage. The medical exam, the police certificates, the DS-160, the Form I-134 affidavit of support, and the civil documents your fiance(e) uploads for the embassy all come later, after USCIS approves this petition and sends it to the Department of State. For that half of the journey, see our guide to the documents required for the K-1 fiance visa process and our list of K-1 visa interview questions with sample answers.
Only a U.S. citizen can file Form I-129F. Lawful permanent residents cannot. Both of you must be legally free to marry on the day you file, meaning every prior marriage has already ended by decree, annulment, or death, not that a divorce is pending. You must also intend to marry within 90 days of your fiance(e)’s admission to the United States, and you must have met each other in person within the two years immediately before the filing date. The two-year clock runs backward from the day you file, not from the day USCIS decides.

Two things changed recently and they cause more rejections than anything else on this list. First, USCIS stopped taking paper checks and money orders through the mail on Oct. 28, 2025. A mailed I-129F now has to be paid by card using Form G-1450 or by bank debit using Form G-1650, unless you qualify for an exemption and file Form G-1651 on top of the package. Second, Form I-129F still cannot be filed online. It is not on either of the USCIS online-filing lists, so a paper package mailed to Dallas is the only route.
The other frequent failure is thin evidence of the in-person meeting. This is the single requirement where a shortfall does not produce a Request for Evidence but an outright denial. The regulation is blunt about it: failure to establish that you met within the required period, or that the requirement should be waived, “shall result in the denial of the petition.” The denial is without prejudice, so you can refile after you meet, but you lose the fee and roughly a year.
Below, every item is graded. Required means USCIS asks for it by name and the package is incomplete without it. Recommended means it is not on the official list but it is what closes an RFE or satisfies the consular officer later. Situational means it applies only if your facts match. Work through the categories in order, build the package in that order, and index it in a cover letter so an officer can find any item in seconds.
1. Form I-129F, the Fee, and the Payment Authorization
Form I-129F, edition 01/20/25, fully completed
Download it fresh the week you file. Every page must carry the same edition date at the bottom; a package assembled from two editions gets rejected. USCIS rejects outright if any of these fields are blank: Part 1 classification sought, family name, mailing address, and date of birth; Part 2 classification sought, family name, and date of birth. Write “N/A” or “None” rather than leaving a box empty.
Official USCIS Form I-129F page
Your handwritten ink signature
USCIS will not accept a stamped or typewritten name in place of a signature and will reject an unsigned petition. A photocopy, fax, or scan is acceptable so long as it reproduces an original handwritten ink signature. Only the petitioner signs the I-129F; your fiance(e) does not.
Filing fee of $675
That is the general I-129F filing fee in the current USCIS fee schedule,
Form G-1055, edition 05/29/26. There is one exception: if you are filing for K-3 status for a spouse on the basis of a
Form I-130 you already filed, the fee is $0. There is no biometrics fee and no fee waiver route for a standard K-1 petition.
Form G-1450 or Form G-1650 payment authorization
Since Oct. 28, 2025 a mailed benefit request can only be paid electronically. Use Form G-1450 to authorize a credit, debit, or prepaid card, or Form G-1650 to authorize an ACH debit from a U.S. bank account. Clip the authorization to the front of the package. Do not mail a personal check or money order without the exemption form below; the package will be rejected and returned.
Form G-1450, credit card authorization
Form G-1651, exemption for paper fee payment
Only if you genuinely cannot pay electronically. You must certify that you lack access to banking or electronic payment systems, that electronic payment would cause undue hardship under 31 C.F.R. Part 208, or that a paper transaction is necessary for national security or law enforcement reasons. Place the signed G-1651 on top of the package with your check.
Form G-1651 requirements
Free, one page, and it gets you a text and email with your receipt number within days of the lockbox accepting the package instead of waiting two to four weeks for the paper
Form I-797C. Clip it to the very first page.
Only if an attorney or a DOJ-accredited representative is representing you. Without a G-28 on file, USCIS will not talk to your lawyer about the case.
Rejection Trap
Form I-129F cannot be filed online. It does not appear on the USCIS list of forms you can complete through a guided workflow, and it is not on the PDF-upload list either. If a website offers to “file your I-129F online,” it is a paid preparation service that still prints and mails the same paper package you could mail yourself.
2. Proof That You Are a U.S. Citizen
USCIS needs one document from this category, not all of them. A copy of an unexpired U.S. passport is the cleanest option because it proves identity and citizenship on one page. Use an alternative only if you do not have a valid passport.
Copy of your valid, unexpired U.S. passport
Copy the biographic page showing your photo, name, date of birth, and the issue and expiration dates. One catch that trips people up: the instructions specify a passport or passport card “issued with a validity period of at least five years.” A limited-validity emergency passport or a child’s short-validity book does not satisfy this item on its own.
Copy of your U.S. birth certificate
Use this if you have no passport. It must be issued by a U.S. civil registrar, vital statistics office, or other civil authority and show that you were born in the United States. A hospital souvenir certificate is not acceptable. Order a certified copy from the vital records office in the state of birth.
Copy of your Certificate of Naturalization
For naturalized citizens. Copy the original certificate issued by USCIS or the former Immigration and Naturalization Service. Photocopying a naturalization certificate for an immigration filing is expressly permitted.
Copy of your Certificate of Citizenship
For people who acquired or derived citizenship through a parent and hold Form N-560 or N-561. If you have a passport as well, send the passport copy instead and keep this in reserve.
Certificate of citizenship vs. U.S. passport
For citizens born overseas to U.S. citizen parents. The FS-240 is issued by a U.S. embassy or consulate and is accepted in place of a domestic birth certificate.
Statement from a U.S. consular officer
A last resort if you are abroad without any of the documents above. The statement must be executed by a consular officer, certify that you are a U.S. citizen, and confirm that you hold a currently valid U.S. passport. Unlike everything else in this package, this one is submitted as an original.
3. Proof You Met in Person Within Two Years
This is the requirement that decides more I-129F cases than any other. USCIS wants to see that you and your fiance(e) were physically in the same place at the same time at some point during the two years immediately before the filing date. Video calls do not count. Meeting the family does not count. A trip that is one week outside the two-year window does not count.
Passport pages showing entry and exit stamps
Copy the biographic page plus every page carrying a stamp from the trip. This is the strongest single piece of evidence because it is a government record of your physical presence in your fiance(e)’s country on specific dates. If your fiance(e) traveled to you instead, copy their passport pages and their U.S. entry stamp or I-94.
Flight tickets, e-ticket receipts, or boarding passes
Print the airline confirmation showing your name, the route, and the dates. Boarding passes are better than a booking email because they show the flight was actually taken. Airlines keep a trip history in your frequent-flyer account for several years if you deleted the original email.
Dated photographs of the two of you together
Six to ten is plenty. Pick photos with an identifiable background: a landmark, a restaurant sign, a family gathering. Label each one on a separate caption sheet with the date, the city, and who is in the frame. Do not write on the back of photos you are submitting as relationship evidence.
Hotel or rental reservations and receipts
A booking in both names for the dates of the visit ties the two of you to the same address on the same nights. Hotel folios, Airbnb receipts, and car rental agreements all work.
A signed written statement describing the meeting
The instructions expressly list “a written statement from you and/or your fiance(e) stating the circumstances of your meeting” as acceptable evidence. One page, first person, with dates and place names. A sample is included further down this page.
Card or bank statements showing charges abroad
Highlight the foreign-currency transactions from the trip dates and black out the account number. Restaurant, taxi, and pharmacy charges in your fiance(e)’s city are quiet, hard-to-fake corroboration.
Cultural-custom exception evidence
Only if you have not met and cannot. You must show that meeting in person would violate strict and long-established customs of your fiance(e)’s foreign culture or social practice, and separately that every other aspect of the traditional arrangement has been or will be honored. Typical filings include a statement from a religious or community authority describing the custom, the arranged-marriage agreement between the families, and country-condition material. This is a discretionary exemption and it is granted sparingly.
Extreme-hardship exception evidence
Only if traveling to meet would cause extreme hardship to you, the petitioner. The hardship has to be yours, not your fiance(e)’s. Medical records from a treating physician establishing that you cannot fly, military deployment orders, or documentation of a disability are the usual proof. Cost, work schedules, and visa refusals for the beneficiary do not meet the standard.
Denial, Not an RFE
Under 8 CFR 214.2(k)(2), failing to establish the in-person meeting, or that it should be waived, results in denial of the petition. The denial is without prejudice, so you may file a new petition once you have met, but you forfeit the $675 and start the queue over. If your last trip is close to the two-year edge, take another trip before you file rather than filing against a stale stamp.
4. Statements of Intent to Marry Within 90 Days
Both of you have to state, in writing, that you intend to marry each other within 90 days of the K-1 entry. USCIS does not publish a template. The instructions say evidence of intent “may include statements of intent to marry signed by both you and your fiance(e) or any other evidence that establishes, by a preponderance of the evidence, your mutual intention.” Two short signed letters are the standard way to satisfy it, and they take fifteen minutes.
Your signed and dated statement of intent to marry
One page, addressed to USCIS, naming your fiance(e), confirming you are both legally free to marry, and stating explicitly that you intend to marry within 90 days of admission on a K-1 visa. Sign it in ink and date it within a few weeks of the filing date.
Your fiance(e)’s signed and dated statement of intent to marry
Same content, written in the first person by the beneficiary. A scan or photograph of the signed page is fine; the original does not need to travel. The two letters should not be word-for-word identical, which is a pattern officers notice.
Certified English translation of the beneficiary’s statement
Required if your fiance(e) writes in another language. Attach the translation and the translator’s certification directly behind the original letter.
Corroborating wedding-planning evidence
A venue inquiry or deposit receipt, an email thread with an officiant, an engagement announcement, a jeweler’s receipt for the ring, or a message thread where you discuss dates. Two or three items are enough to turn a pair of assertions into a documented plan.
Sample Statements of Intent to Marry
Use these as structure, not as text to copy. Officers see the same recycled paragraphs constantly, and two identical letters signed by two different people read as manufactured. Replace every bracketed field, keep the specifics that only you would know, and keep each letter under one page.

Why the Third Letter Helps
The meeting statement is the cover sheet an officer reads before flipping through your stamps and boarding passes. It turns a stack of loose paper into a dated narrative and tells the officer exactly which tab proves which trip. It also carries forward: the consular officer at the interview reads the same file.
5. Evidence That Prior Marriages Legally Ended
Final divorce decree for each of your prior marriages
A copy of the final decree, issued by a civil authority, for every prior marriage. Not the petition, not the separation agreement, not an interim order: the final decree with the judge’s signature and the entry date. If you were married three times, send three decrees.
Final divorce decree for each of your fiance(e)’s prior marriages
Same rule on the beneficiary’s side, obtained from the court or civil registry in the country where the marriage ended, with a certified English translation. In several countries the divorce is recorded on a family register or civil status certificate rather than a decree; submit the official document that country issues, with a translation.
Annulment order
If a prior marriage was annulled rather than dissolved. A religious annulment does not end a marriage in the eyes of USCIS; you need the civil order.
Death certificate for a deceased prior spouse
Issued by the civil authority in the place of death, with a certified translation if it is not in English.
Legally Free to Marry Means Now
Both of you must already be divorced on the day the petition is filed. A pending divorce, a filed-but-not-final petition, or a decree that becomes final next month all fail the test, and USCIS will deny rather than hold the case. If a decree is only weeks away, wait and file after it is entered.
6. Photographs and Identity Documents
One color passport-style photograph of you
Note the count: the current instructions ask for one photo of each person, not two. It must be taken within 30 days of filing, measure 2 by 2 inches, be in color with a full-face frontal view on a white to off-white background, and be printed on thin paper with a glossy finish, unmounted and unretouched. Head height must be 1 to 1 3/8 inches from the top of the hair to the bottom of the chin, and eye height 1 1/8 to 1 3/8 inches from the bottom of the photo. Your head must be bare unless you wear religious headwear. Print your name and A-number, if you have one, lightly on the back in pencil or felt pen.
One color passport-style photograph of your fiance(e)
Identical specification, also taken within 30 days of the filing date. Have your fiance(e) get it printed locally to U.S. passport-photo dimensions and courier it, or have them email a compliant digital file and print it yourself on glossy photo paper. Label the back the same way.
U.S. visa photo dos and don’ts
Evidence of a legal name change
Required if either of you uses a name that differs from the name on the other documents in the package. Acceptable proof is a marriage certificate, an adoption decree, or a court order. This is a very common quiet RFE trigger when a petitioner’s birth certificate carries a maiden name.
Using a marriage certificate to update records
If CBP or USCIS ever issued you or your beneficiary a Form I-94, enter the number and the date the authorized stay expires on the petition. Retrieve a lost record from the CBP I-94 website; if it is not there,
Form I-102 is the replacement route.
Copy of your fiance(e)’s passport biographic page
Not on the official checklist, but the form asks for passport and travel document numbers, and a legible copy of the biographic page lets the officer confirm the spelling of the name and the date of birth exactly as they appear on the travel document. Name mismatches between the petition and the passport cause avoidable trouble at the consular stage.
7. IMBRA Disclosures and the Multiple-Filing Waiver
The International Marriage Broker Regulation Act is the part of the I-129F almost nobody reads until USCIS asks about it. It does two things. It forces the petitioner to disclose protection orders and convictions for a defined list of crimes, and it caps how often one person can petition for a fiance(e). USCIS maintains a database of multiple I-129F filers, notifies you when a second petition you filed is approved, and, once two of your petitions have been approved and you file a third within ten years of the first filing date, notifies your beneficiary of how many petitions you have had approved.
Complete Part 3 criminal-history questions truthfully
You must disclose any temporary or permanent protection or restraining order, civil or criminal, related to a specified crime, and any arrest or conviction for one. The specified list covers domestic violence, sexual assault, child abuse or neglect, dating violence, elder abuse, stalking; homicide, murder, manslaughter, rape, abusive sexual contact, sexual exploitation, incest, torture, trafficking, peonage, hostage taking, involuntary servitude, slave trade, kidnapping, abduction, unlawful criminal restraint, false imprisonment; and three or more convictions relating to a controlled substance or alcohol not arising from a single act. Separately, Part 3 asks about any other arrest, citation, charge, indictment, conviction, fine, or imprisonment in any country, excluding traffic incidents that were not alcohol or drug related and carried a fine under $500.
Certified court and police records for any disclosed offense
If you answered yes, submit certified copies of all court and police records showing the charges and the disposition for every arrest or conviction. The instructions are explicit that you must do this even if the record was sealed, expunged, or otherwise cleared, and regardless of whether a judge, officer, or attorney told you that you no longer have a record. If no record exists, submit a certified statement from the court saying so.
Multiple-filer waiver request, Part 3, Items 5.a through 5.c
You must request a waiver of the IMBRA filing limitations if you have previously filed Form I-129F for two or more fiance(e) beneficiaries, or if you have previously had an I-129F approved and fewer than two years have passed since the filing date of that approved petition. Tick the box for the waiver you are requesting. If you are filing for a spouse under K-3, no waiver is needed: tick Item 5.d and move on.
Evidence supporting the waiver you selected
A general waiver, Item 5.a, applies if you have never been convicted of a violent criminal offense against a person; support it with evidence of why a waiver is appropriate, such as a death certificate, police report, news article, or a licensed physician’s report concerning the death or incapacity of a previous fiance(e) beneficiary. An extraordinary circumstances waiver, Item 5.b, applies if you have such a conviction, and requires evidence of the offense’s nature and circumstances plus evidence of rehabilitation, community ties, or exemplary uniformed service. A mandatory waiver, Item 5.c, is available if you committed violent offenses while being battered or subjected to extreme cruelty by a family member or intimate partner and were not the primary perpetrator; support it with police reports, court records, and evidence of the abuse. You may explain your request in Part 8 or attach a signed, dated letter.
The international marriage broker consent form
If you met your fiance(e) through an international marriage broker, submit the consent form your fiance(e) signed authorizing the broker to release their personal contact information to you, with a certified English translation if it is not in English. A broker is any business that charges fees for dating, matrimonial, matchmaking, or social-referral services between U.S. citizens or residents and foreign nationals. Nonprofit cultural or religious matchmaking organizations are excluded, as are general dating services whose principal business is not international matchmaking and that charge comparable rates to everyone regardless of sex or nationality.
Prepare your fiance(e) for the disclosure
Not a document, but plan for it. If the petition is approved, USCIS sends a copy of your petition, including whatever you disclosed about protection orders and criminal history, to the Department of State for distribution to your fiance(e). USCIS also passes along any criminal background information it finds on its own. Names and contact details of protected persons or victims stay confidential, but your relationship to them, for example spouse or parent, is disclosed. Your fiance(e) should hear it from you first.
Do Not Guess Here
Answering “no” to a Part 3 criminal question about a record you believe was expunged is a misrepresentation, not a technicality, and USCIS runs an FBI records check anyway. If you have any arrest history at all, order the certified disposition before you file and disclose it. If the history involves a specified crime, talk to an immigration attorney before mailing anything.
8. Evidence of a Bona Fide Relationship
Be honest with yourself about this category: relationship evidence beyond the meeting proof and the intent letters is not on the USCIS initial-evidence checklist. USCIS is checking a narrow legal question at this stage. But relationship evidence is the fastest way to shut down a Request for Evidence if one arrives, and the consular officer who interviews your fiance(e) months from now will be looking at the same file with a much broader mandate. Twenty well-chosen pages here cost you nothing and can save a year.
A curated sample of messages
Ten to fifteen pages spread across the relationship, not a thousand-page dump. Pick threads that show ordinary shared life: plans, family news, arguments about the wedding budget. Make sure the timestamps and both names or handles are visible in the screenshots.
Call and video-call logs
A phone bill or app export showing regular international calls over months is dry, dated, third-party evidence, which is exactly what officers weight most heavily. Highlight the relevant lines and redact account numbers.
Dated photographs across the relationship
Different places, different seasons, other people in some of them. Ten to twelve with a caption sheet giving the date, location, and names. Avoid duplicates from a single afternoon.
Money transfer receipts
Remittance receipts, gifts, or shared expenses show financial interdependence, which is one of the classic bona fide markers. Include the sender and recipient names on the receipt.
The strongest bona fide relationship evidence
Sworn affidavits from people who know you both
Two or three, from friends or relatives who have met you both in person, stating how they know you, what they have observed, and their contact details, signed and dated. Generic character references add nothing; specific first-hand observations do.
Evidence you were introduced to each other’s families
Photos with parents or siblings, a group video call screenshot, an engagement gathering, or a message thread with a future in-law. In many K-1 cases this is the detail the consular officer probes hardest.
9. Translations, Copies, and Package Assembly
Certified English translation for every non-English document
Every foreign-language document needs a full English translation plus a signed certification from the translator stating that the translation is complete and accurate and that the translator is competent to translate from that language into English. The translator does not have to be licensed or notarized, but cannot be the petitioner or the beneficiary. A workable certification reads: “I certify that I am competent to translate from [language] into English and that the above translation of the attached document is complete and accurate to the best of my knowledge and ability.” Sign, date, print the name and address, and staple it behind each translated document.
Copies, not originals
Do not send original documents unless the form instructions or a regulation specifically ask for them. USCIS does not routinely return originals. The one exception in this package is the consular officer’s citizenship statement, which is submitted as an original if you are using it.
Cover letter with an itemized index
One page listing every enclosure in the order it appears, with tab numbers. Put the petitioner and beneficiary names, the form number, and a contact phone at the top. It costs ten minutes and it is what makes the meeting statement’s tab references work.
Binder clips, not staples; single-sided printing
The lockbox scans everything, so a heavily stapled package slows intake. Print single sided in black ink. Do not include anything with electronic chips or batteries, no CD-ROMs, DVDs, thumb drives, toys, or action figures, no biological or DNA samples, and no graphic photographs of childbirth or intimate relations. USCIS will not accept those materials.
Statement of unavailability plus secondary evidence
If a primary document genuinely does not exist, for example a birth record in a country whose registry was destroyed, submit a statement from the appropriate civil authority certifying that the primary evidence is unavailable, then secondary evidence such as church or school records, baptismal certificates, or U.S. census records. If secondary evidence is also unavailable, submit two or more sworn affidavits from people who are not parties to the petition, who were alive at the time of the event, and who have direct personal knowledge of it.
10. Where and How to Mail the Package
USPS address, USCIS Dallas lockbox
USCIS, Attn: I-129F, P.O. Box 660151, Dallas, TX 75266-0151. Every I-129F goes here regardless of where you live in the United States. There is no service-center direct-filing option and USCIS cannot adjudicate this form at an international office.
Verify the address before mailing
Courier address for FedEx, UPS, and DHL
USCIS, Attn: I-129F (Box 660151), 2501 South State Highway 121 Business, Suite 400, Lewisville, TX 75067-8003. Couriers cannot deliver to a P.O. box, so use this street address if you want tracked, signed delivery.
Tracking receipt and a complete copy of the package
Scan or photocopy every page you mail, including the signed form and the payment authorization, before it goes in the envelope. Keep the tracking number. If the package is lost or you later need to answer an RFE, the copy is the only record you have.
Order of Assembly
Top to bottom: Form G-1145, then Form G-1450 or G-1650 (or G-1651 with a check), then Form G-28 if you have counsel, then the cover letter and index, then the signed Form I-129F, then the tabbed evidence in the order of this checklist. Address the envelope to the lockbox, not to a service center.
What Is Deliberately Not in This Package
Half the I-129F questions people ask are about documents that belong to a later stage. Sending them early does not speed anything up and can bury the officer in paper.
Form I-134, Declaration of Financial Support. Financial evidence is not on the USCIS initial-evidence checklist for the I-129F. Income proof, tax transcripts, pay stubs, and employer letters belong to the consular stage, where the officer applies the public charge test. Do not send tax returns with the petition.
The medical examination. Your fiance(e) sees a panel physician designated by the embassy after the case reaches the consulate, not before.
Police certificates and the DS-160. Both are consular-stage items. The DS-160 is completed online once the National Visa Center assigns a case number and the embassy issues instructions.
Form I-485 and Form I-765. Adjustment of status and the work permit come after the wedding, filed from inside the United States. K-1 and K-2 holders are authorized to work incident to status for the authorized period of stay, but must apply separately for an employment authorization document.
A separate petition for your fiance(e)’s children. A child who is unmarried and under 21 can follow the K-1 parent as a K-2 nonimmigrant without a separate petition. List each child on the I-129F.
After You File
Expect Form I-797C, the receipt notice, within two to four weeks, or a text and email within days if you included Form G-1145. Keep the receipt number; it is how you track the case and how you respond to anything USCIS sends. Current wait times move constantly, so check the USCIS processing times tracker against your receipt date rather than relying on a figure you read months ago.
USCIS may schedule you for a biometrics appointment. At it you will sign an oath reaffirming that you provided or authorized all the information in the petition and that it is complete, true, and correct under penalty of perjury. If you cannot make that attestation in good faith on the day, USCIS will send you back for another appointment rather than take a bad oath.
If an RFE arrives, read exactly what is being asked and answer only that, with the full response in one package before the deadline. Our guide on what to do after a USCIS RFE covers the mechanics.
An approved I-129F is valid for four months from the date of approval under 8 CFR 214.2(k)(5). If it expires while the case sits at the National Visa Center or the embassy, a USCIS director or a consular officer can revalidate it for another four months on a finding that you are both still free to marry and still intend to marry within 90 days of entry. Approval terminates automatically if the petitioner dies or files a written withdrawal before the beneficiary arrives. Once your fiance(e) has been admitted in K status, the petition can no longer be withdrawn.
From there the case moves to the Department of State, then to the embassy or consulate you named on the petition. That is where the second document list begins, and where the K-1 interview questions start to matter.
Frequently Asked Questions
What documents do I need to file Form I-129F?
USCIS asks for proof of your U.S. citizenship, proof that any prior marriages legally ended, one passport-style photo of each of you taken within 30 days of filing, evidence of a legal name change if applicable, and, for a K-1, evidence you intend to marry within 90 days and met in person within the two years before filing. An IMBRA waiver is added only if you are a repeat filer.
How much is the I-129F filing fee in 2026?
The general filing fee is $675, per the current USCIS fee schedule, Form G-1055, edition 05/29/26. If you are filing for K-3 status for a spouse based on a Form I-130 you already filed, the fee is $0. There is no separate biometrics fee for the I-129F.
Where do I mail Form I-129F?
All I-129F petitions go to the USCIS Dallas lockbox. By U.S. Postal Service: USCIS, Attn: I-129F, P.O. Box 660151, Dallas, TX 75266-0151. By FedEx, UPS, or DHL: USCIS, Attn: I-129F (Box 660151), 2501 South State Highway 121 Business, Suite 400, Lewisville, TX 75067-8003. There is no service-center direct-filing option.
Can I file Form I-129F online?
No. Form I-129F is not on either USCIS online-filing list, neither the guided-workflow list nor the PDF-upload list. A paper package mailed to the Dallas lockbox is the only route. Websites that advertise online I-129F filing are preparation services that still print and mail the same paper package.
Can I still pay the I-129F fee by check?
Not by default. Since Oct. 28, 2025 USCIS accepts only electronic payment on mailed filings: a card authorization on Form G-1450 or an ACH debit on Form G-1650. A paper check is accepted only if you qualify for an exemption and place a signed Form G-1651 on top of the package.
What proof do I need that we met in person within two years?
Passport pages showing entry and exit stamps plus flight tickets or boarding passes are the core. Add dated photos together, hotel receipts, foreign card charges, and a signed statement describing the trip. The two-year clock runs backward from the filing date, and failing this requirement causes a denial rather than a Request for Evidence.
Do I need to send financial documents with the I-129F?
No. Income proof, tax transcripts, pay stubs, and Form I-134 are not on the USCIS initial-evidence checklist for the I-129F. Financial support is assessed later at the consular stage. Sending tax returns with the petition adds paper without adding value.
When does IMBRA require a multiple-filing waiver?
You must request one if you previously filed Form I-129F for two or more fiance(e) beneficiaries, or if you previously had an I-129F approved and fewer than two years have passed since that petition’s filing date. Choose the general, extraordinary circumstances, or mandatory waiver in Part 3 and attach supporting evidence. No waiver is needed when filing for a spouse.
How long is an approved I-129F valid?
Four months from the approval date under 8 CFR 214.2(k)(5). A USCIS director or a consular officer can revalidate an expired petition for another four months on finding that you are both still free to marry and still intend to marry within 90 days of entry. Approval terminates automatically if the petitioner dies or withdraws the petition.
