An I-751 affidavit is a signed statement from someone who knows you and your spouse, describing what they have personally seen of your marriage. USCIS lists these statements as optional supporting evidence for Form I-751, Petition to Remove Conditions on Residence. If you use them, the form instructions ask for affidavits from at least two people who have known both of you since your conditional residence was granted.
Affidavits help most when your paper trail is thin. That covers couples who kept separate bank accounts, recently moved in together after a long-distance stretch, live with parents and have no lease, or split utility bills in one name. They do not replace joint documents. The I-751 instructions say so directly: affidavits “must be supported by other types of evidence.”
The rules for what goes inside an affidavit are short and specific. USCIS wants the writer’s full name and address, date and place of birth, relationship to you or your spouse, and “full information and complete details explaining how the person acquired his or her knowledge” of your marriage. The last item is where most affidavits fail. A paragraph saying the couple is “very much in love” adds almost nothing. A paragraph describing the Thanksgiving the writer hosted, who cooked, and how the couple talked about buying a house adds a lot.

The stakes are high. If no I-751 is filed, conditional permanent residence ends automatically two years after it was granted, and the holder becomes removable. A properly filed petition gets a receipt notice that extends the green card for 48 months past its expiration date while USCIS decides the case.
USCIS may also call the people who sign affidavits. The instructions warn that affiants “may be required to testify before an immigration officer” about what they wrote. Every sentence in the statement should be something the writer can repeat calmly in an interview.
Know What USCIS Actually Requires
The requirements come from the evidence section of the Form I-751 instructions (edition 04/01/24, the current edition). Third-party affidavits are item 5 on the list of examples of “good faith” marriage evidence, after children’s birth certificates, leases or mortgages, and joint financial records. That order matters. Officers read affidavits as corroboration of the documents, not as a substitute for them.
Every affidavit you submit should contain each element below. Missing any one of them gives an officer a reason to give the statement little weight.
- Full legal name of the person making the affidavit (the affiant)
- Affiant’s full current address
- Affiant’s date of birth and place of birth
- Relationship to you or your spouse, if any (friend, mother, landlord, coworker)
- How and when the affiant met each of you, and how they know about your marriage
- Specific events the affiant witnessed, with dates and places
- A sworn or affirmed signature: either notarized, or signed under penalty of perjury and dated
- The affiant’s phone number or email (not required, but useful if USCIS wants to verify)
Read the evidence list in the official instructions once before you collect anything. Our I-751 documents guide breaks the full package down item by item.
Choose the Right People to Write Them
The instructions describe the ideal affiant: someone who has known both of you since your conditional residence began and has personal knowledge of your marriage. A friend who met your spouse once at the wedding does not meet that description. A neighbor who has watched you walk the dog together every evening for two years does.
Family members are allowed. Officers know a mother has a stake in the outcome, so a parent’s affidavit should lean on concrete, checkable detail: visits, holidays, phone calls with both spouses, help with a move. Friends, landlords, coworkers, neighbors and religious leaders carry more independent weight because they gain nothing from the approval.
| Affiant | Why it helps or hurts | Strength |
|---|---|---|
| Landlord or property manager | Can confirm both spouses live at the address, signed or paid together | Strong |
| Close friend who sees you often | Independent witness to daily life, trips, holidays | Strong |
| Neighbor | Sees the couple coming and going from one home | Strong |
| Coworker of either spouse | Has met the other spouse at work events or at home | Good |
| Parent or sibling | Knows the relationship well but has a personal stake | Good with detail |
| Pastor, imam, priest or rabbi | Can describe the couple’s joint participation over time | Good |
| Someone who met you once | No personal knowledge of the marriage over time | Weak |
| Your attorney or preparer | Not a witness to the relationship | Do not use |
If you are filing alone because of divorce, death or abuse, affidavits become more important. In those waiver cases the question is whether you entered the marriage in good faith, so people who knew you both at the start of the marriage are the most valuable witnesses. The divorce itself does not have to be explained by them.
Decide How It Will Be Signed
The I-751 instructions ask for affidavits “sworn to or affirmed.” There are two common ways to meet that. The traditional route is a notarized affidavit, signed in front of a notary public. The second route is an unsworn declaration under 28 U.S.C. 1746, a federal law that lets a written statement signed “under penalty of perjury” stand in for a sworn affidavit “with like force and effect” wherever federal rules call for one.
Many immigration practitioners file I-751 statements as Section 1746 declarations without a notary. A notarized affidavit removes any question about form and costs little in the U.S. (many banks notarize free for customers). For a parent abroad, a Section 1746 declaration avoids a trip to a consulate. The law sets different wording depending on where the person signs.
| Method | Closing wording | Best for |
|---|---|---|
| Notarized affidavit | Signed in front of a notary, who adds a jurat and seal | Anyone in the U.S. with easy notary access |
| Section 1746, signed in the U.S. | “I declare under penalty of perjury that the foregoing is true and correct. Executed on (date).” | Friends, landlords and coworkers in the U.S. |
| Section 1746, signed abroad | “I declare under penalty of perjury under the laws of the United States of America that the foregoing is true and correct. Executed on (date).” | Parents and relatives living outside the U.S. |
Signing “under penalty of perjury” is a real legal exposure. A false statement in an I-751 affidavit can lead to perjury or immigration fraud findings against the writer, and a denial and removal proceedings for you. Never ask anyone to state something they did not see.
Write It: Structure That Officers Can Use
A strong affidavit runs one to two pages. It reads like a witness statement, not a character reference. Use this order:
- Title: “Affidavit of [Full Name] in Support of Form I-751 for [Petitioner Name] and [Spouse Name]”
- Identity: full name, address, date and place of birth, occupation, immigration status if useful (for example “U.S. citizen”)
- Relationship: how the writer knows each spouse and since when
- Observations: 3 to 6 specific events with month and year, places, and what the writer saw
- Living arrangement: anything the writer knows first-hand about the shared home
- Offer to testify: a line saying the writer can be contacted, with phone or email
- Signature block: notary jurat, or the Section 1746 declaration with date and signature
Concrete detail is what separates useful statements from filler. “They are a loving couple” proves nothing. “In July 2025 they stayed with us for four days in Austin, shared the guest room, and talked about saving for a house in Dallas” is something an officer can weigh and a witness can repeat.
Keep it in the writer’s own voice. Officers read thousands of these, and identical phrasing across three affidavits suggests the couple wrote them. If the writer is not comfortable in English, they should write in their own language and you should attach a certified English translation (see Step 5).
Sample I-751 Affidavits
The three samples below show the structure in practice for three different kinds of witness: a friend in the U.S. signing under Section 1746, a mother in India signing under the overseas Section 1746 wording, and a landlord signing in front of a notary. Names, dates and places are fictional.
These samples are illustrations of structure and level of detail. USCIS fraud units flag recycled language, and an affidavit is only credible when it describes what the writer actually witnessed, in their own words.
Affidavit of Daniel R. Okafor in Support of Form I-751 for Priya Sharma and Michael Chen
I, Daniel R. Okafor, was born on March 14, 1990, in Houston, Texas. I live at 2214 Elmwood Drive, Austin, TX 78704. I am a U.S. citizen and work as a high school science teacher. I make this declaration in support of the petition of Priya Sharma and Michael Chen to remove the conditions on Priya’s residence.
I have known Michael since 2014, when we were roommates at the University of Texas. I met Priya in February 2022, when Michael brought her to my birthday dinner and introduced her as his girlfriend. Since then I have seen them together at least once or twice a month.
I attended their wedding at the Travis County Courthouse on June 3, 2023, and signed as one of their two witnesses. Afterward my wife and I hosted a small reception for them at our home.
Since the wedding, I have visited their apartment at 1180 Riverside Drive, Austin, many times. Both of their names are on the mailbox, and Priya’s work bag and Michael’s bike are always in the hallway. In November 2024 and November 2025 they hosted Thanksgiving for our group of friends; Priya cooked and Michael carved, as he does every year.
In July 2025, my wife and I traveled with them to Big Bend National Park for four days. They shared a cabin and talked with us about saving to buy a house in 2027. In March 2026 I helped them move a new couch into their apartment.
I am willing to answer questions from USCIS about anything in this statement. I can be reached at (512) 555-0147 or [email protected].
I declare under penalty of perjury that the foregoing is true and correct. Executed on September 28, 2026.

Affidavit of Lakshmi Sharma in Support of Form I-751 for Priya Sharma and Michael Chen
I, Lakshmi Sharma, was born on August 22, 1964, in Pune, Maharashtra, India. I live at Flat 7, Shanti Apartments, Kothrud, Pune 411038, India. I am a retired bank officer and a citizen of India. I am the mother of Priya Sharma.
Priya told me about Michael in early 2022 and introduced us on a video call in April 2022. Since then I have spoken with both of them by video almost every Sunday. Michael often joins the call first and shows me what they cooked that week.
I traveled to the United States on a visitor visa and attended their wedding in Austin on June 3, 2023. I stayed with them for six weeks, from May 20 to July 1, 2023. They gave me their bedroom and slept in the living room.
From December 2024 to January 2025, Priya and Michael visited me in Pune for three weeks. Michael met our extended family at my nephew’s wedding on December 28, 2024, and stayed with Priya in my home for the entire visit.
I know from our calls that they live together in Austin. When I sent a parcel for Diwali in October 2025, I addressed it to both of them at their apartment, and Michael called to thank me when it arrived.
I am willing to answer questions from USCIS about this statement. I can be reached at +91 98xxx xxxxx or [email protected].
I declare under penalty of perjury under the laws of the United States of America that the foregoing is true and correct. Executed on September 25, 2026.

Affidavit of Rosa M. Delgado in Support of Form I-751 for Priya Sharma and Michael Chen
I, Rosa M. Delgado, being first duly sworn, state as follows. I was born on January 9, 1971, in San Antonio, Texas, and live at 45 Lakeview Court, Austin, TX 78745. I am the owner and manager of the four-unit building at 1180 Riverside Drive, Austin, TX 78741.
Priya Sharma and Michael Chen applied together to rent Unit 3 in July 2023. I interviewed them together, and both signed the lease that started on August 1, 2023. They renewed the lease together in 2024, 2025 and 2026.
I live nearby and visit the building at least weekly. I regularly see Priya and Michael coming and going together. When the water heater in Unit 3 failed in January 2025, Michael called me and Priya let the plumber in the next morning. Both of them have contacted me about maintenance at different times.
Rent is paid each month from an account in both of their names. I have never had reason to believe anyone other than the two of them lives in Unit 3.
I am willing to speak with USCIS about this statement and can be reached at (512) 555-0193.

Notice what all three share: dates, addresses, and events another person could confirm. None of them argues the law or says the marriage “is not for immigration purposes.” That conclusion belongs to the officer. The writer’s job is to describe what they saw.

Decide How Many to Include
USCIS sets a floor, not a ceiling. If you rely on affidavits, the instructions call for statements from at least two people. There is no official maximum and no rule that more is better.
In our reading of how these packets are built, two to four detailed affidavits from different parts of your life (one friend, one landlord or neighbor, one family member) carry more weight than eight short ones from relatives. If your joint documents are strong, two good affidavits are enough. If your documents are thin, add more independent witnesses rather than more family.
Before deciding, list your joint documents against the bona fide marriage evidence list. Affidavits should fill specific gaps, such as a period with no shared lease.
Add Translations and Supporting Proof
Any affidavit written in a language other than English needs a full English translation. Under the I-751 instructions (and 8 CFR 103.2(b)(3)), the translator signs a certification that the translation is complete and accurate and that they are competent to translate from that language into English. The certification includes the translator’s signature, printed name, date and contact information. The instructions do not require a notary for the certification. Using an independent translator, rather than you or your spouse, avoids questions about the translation’s accuracy.
Optional but helpful attachments include a copy of the affiant’s photo ID or passport bio page and two or three dated photos of the affiant with both spouses. Label each attachment with the affiant’s name so the officer can match it to the statement.
File Them With Your I-751
Joint petitions must be filed during the 90-day period immediately before the expiration date on the two-year green card. Waiver petitions (divorce, death of the spouse, abuse) can be filed any time after conditional residence begins and before removal.
USCIS currently accepts Form I-751 online or on paper. For a paper filing, the instructions say the original affidavit must be submitted, so mail the wet-ink originals and keep copies. For an online filing, upload clear scans of the signed affidavits and keep the originals in case USCIS asks for them. In August 2026, DHS issued an interim final rule letting USCIS require online filing for any form that has been available for e-filing for at least 180 days, with 60 days’ public notice. Check the I-751 page before you file.
| Paper filing | $750 |
| Online filing | $700 |
| Waiver based on battery or extreme cruelty | $0 |
| Separate biometrics fee | None |
| Typical joint filing, online | $700 |
Some filers may qualify for a fee waiver with Form I-912, which must be filed on paper. Fees change, so confirm the amount on the USCIS fee schedule on the day you file.
Common Mistakes That Weaken I-751 Affidavits
“I believe their marriage is real” is a conclusion. Officers want what the writer saw: the trip, the move, the shared apartment, the hospital visit.
Leaving out the writer’s date and place of birth or full address skips items the instructions name specifically.
Three statements with the same sentences suggest the couple drafted them, which undercuts every one of them.
Relatives are allowed, but a packet with only parents and siblings looks one-sided. Add at least one independent witness.
If an affidavit says you moved in together in May and the lease says August, expect questions. Check every date against your other evidence.
A Section 1746 statement needs the penalty-of-perjury sentence, a date and a signature. A parent abroad must use the “under the laws of the United States of America” wording.
Affidavits must be supported by other evidence. Without joint records, even excellent statements rarely carry a petition.
After You File
Your receipt notice (Form I-797) extends your conditional green card for 48 months past its printed expiration date, and it works with the card as proof of status for travel and employment. If the case is still pending after that, USCIS tells petitioners to call the Contact Center at 800-375-5283.
USCIS may decide the case on paper or schedule an interview. Keep copies of every affidavit you submitted, and let each affiant know they could be contacted. Our guide to filing the I-751 within the 90-day window covers the full timeline, and if you travel while the case is pending, read returning with a conditional green card first.
Frequently Asked Questions
How many affidavits do I need for Form I-751?
If you submit affidavits, the I-751 instructions ask for statements from at least two people who have known both spouses since conditional residence was granted. There is no official maximum. Two to four detailed affidavits from different kinds of witnesses usually work better than many short ones from relatives.
Do I-751 affidavits have to be notarized?
The instructions ask for affidavits sworn to or affirmed. A notarized affidavit meets that. Federal law at 28 U.S.C. 1746 also lets a written statement signed under penalty of perjury and dated stand in for a sworn affidavit, and many practitioners file I-751 statements that way.
Can my parents write an affidavit for my I-751?
Yes. Family members are allowed, but officers know they have a personal stake, so their statements should rely on concrete details such as visits, holidays and calls with both spouses. Parents abroad can sign a Section 1746 declaration using the wording for statements executed outside the United States.
What information must an I-751 affidavit include?
USCIS asks for the affiant’s full name and address, date and place of birth, relationship to you or your spouse, and full details explaining how the person knows about your marriage. Specific events with dates and places carry the most weight.
Can I-751 affidavits replace joint bank accounts or a lease?
No. The I-751 instructions state that affidavits must be supported by other types of evidence. They fill gaps in a record that already includes documents such as a shared lease, joint accounts, joint tax returns or insurance naming the spouse.
Will USCIS contact the people who wrote affidavits?
It can. The I-751 instructions say affiants may be required to testify before an immigration officer about the information in their affidavit. Every statement should describe only what the writer personally saw and can repeat.
What if the affidavit is not in English?
Attach a full English translation. The translator must certify that the translation is complete and accurate and that they are competent to translate, and include their signature, printed name, date and contact information.
Do I send original affidavits with an online I-751?
For paper filing, the instructions call for the original affidavit, so mail the signed originals. For online filing, upload clear scans of the signed statements and keep the originals, because USCIS may ask to see them later.
