Bona Fide Marriage Evidence Checklist: I-130, I-485 and I-751

USCIS approves a marriage-based case when the file shows, more likely than not, that the couple married in good faith to build a life together. No single document proves that. Officers read the whole record: a shared home, money that moves between both of you, insurance and tax records that name each other, and people who know you as a couple. This checklist sorts that evidence by the three points where USCIS reviews it: the Form I-130 petition, the Form I-485 green card application and interview, and the Form I-751 petition to remove conditions two years later.

The legal test comes from the USCIS Policy Manual, Volume 6, Part B, Chapter 6. A petitioner must show the marriage was bona fide “at the beginning of the marriage,” meaning the spouses intended to build a life together when they married. USCIS does not judge whether the marriage will last. A couple going through a rough patch can still be approved if the marriage was genuine at the start.

The evidence types themselves are written into federal regulations. 8 CFR 204.2(a)(1)(iii)(B) lists joint ownership of property, a lease showing a shared home, commingled finances, birth certificates of children, sworn affidavits from people who know the couple, and any other relevant documents. 8 CFR 216.4(a)(5) repeats almost the same list for the I-751. The checklist below follows those categories, then adds what the form instructions ask for on top.

Your evidence also has to grow over time. A packet that is strong on the day you file the I-130 can look thin at an interview a year later if nothing new has been added. By the I-751, USCIS wants proof covering the period since you became a conditional resident, not the wedding photos you sent two years earlier. Each stage below lists what to add.

If your marriage is less than two years old on the day you become a permanent resident, your green card is conditional and valid for two years. You and your spouse must then file the I-751 jointly in the 90 days before the card expires. A properly filed I-751 receipt notice extends your status and work authorization for 48 months beyond the card’s expiration, according to USCIS.

Use this page as a working list. Print it with your browser’s print command (Ctrl+P or Cmd+P), tick off each item as you collect it, and keep copies of everything you send. For the forms themselves, see our Form I-130 documents checklist; this page covers the proof that your marriage is real.

Fees change, and the wrong amount gets a filing rejected. Check the USCIS fee schedule the week you file, especially for work and travel permits filed with an I-485, whose fees depend on your category and filing date. Spouses abroad who go through consular processing pay State Department fees instead of the I-485 fee. Current wait times for each form are on our USCIS processing times page.

Stage 1: Core documents for the I-130 spousal petition

These prove the marriage exists and is legally valid. They are the base of every spousal case, whether the spouse adjusts status in the United States or interviews at a consulate abroad. A marriage license is not enough; USCIS wants the registered marriage certificate.

Stage 1: Bona fide marriage evidence to file with the I-130

This is the part officers weigh most. Send evidence from several categories rather than a thick stack from one. Twenty pages of photos do less than one lease, one joint bank statement and one insurance card with both names. The I-130 instructions list the same six types as the regulation: shared property, a shared lease, combined finances, children’s birth certificates, third-party affidavits and other relevant records.

Strong vs weak evidence: how officers weigh it

Strength comes from two things: how hard a document is to create after the fact, and whether a third party, such as a bank, landlord, employer or government agency, produced it. Documents you made yourself still count, but they work best alongside institutional records.

Stage 2: I-485 package and the green card interview

Spouses of U.S. citizens who are in the United States after a lawful admission or parole can usually file the I-485 with the I-130. The adjustment package also needs the Form I-864 affidavit of support and the Form I-693 medical exam. Those documents prove admissibility and financial support, not the marriage; the marriage evidence is what you filed with the I-130 plus everything that has happened since.

USCIS can interview any petitioner or beneficiary, and the Policy Manual says it will interview when the facts are inconsistent or raise doubt about the marriage. Plan as if you will be interviewed. Officers compare the file with your answers about routines, the home, finances and family, and in some cases interview spouses separately. Our guide to the I-130 marriage interview covers the questions.

What to add over time: an evidence calendar

Think of the file as a running record. Add a few items every few months instead of rebuilding it in a rush before each deadline. The table shows what each period should add.

For how long each stage usually takes for a citizen’s spouse versus a green card holder’s spouse, see our marriage green card timeline.

Stage 3: I-751 evidence to remove conditions

The I-751 is a second bona fide review, and it looks at a different period. The I-751 instructions ask for documents showing the relationship “from the date of the marriage to the present date.” Officers want to see that the shared life documented at the I-130 stage carried on through the conditional years. The form also asks for every address and employer for both spouses since conditional residence began.

USCIS Policy Manual Volume 6, Part I, Chapter 3 governs this stage. The standard is still preponderance of the evidence. An interview is required unless USCIS waives it, and officers may waive it when the record clearly shows a bona fide marriage, there is no sign of fraud, and no complex facts or criminal issues need answers. A complete evidence package is the best route to a waived interview. Our I-751 filing guide walks through the form itself.

Affidavits from friends and family: rules and sample excerpts

An affidavit is a sworn or affirmed statement from someone who knows your marriage firsthand. Under 8 CFR 204.2(a)(1)(iii)(B)(5) and the I-751 instructions, each one must include the writer’s full name and address, date and place of birth, relationship to either spouse, and full details of how they know about the marriage. The writer may be asked to testify about it before an immigration officer, so pick people who would.

Good affiants have seen your life together repeatedly: close friends, neighbors, a landlord, coworkers, relatives, a religious leader. Specific, dated memories carry weight; adjectives do not. “They are a lovely couple” tells the officer nothing. “I have eaten Sunday dinner at their apartment on Elm Street about twice a month since March 2025” tells the officer a lot. Many couples have the affidavits notarized, and the I-751 instructions require the signed originals.

The excerpts below are illustrative. Do not copy their wording; USCIS fraud units notice recycled phrasing, and an affidavit only helps if it is in the writer’s own words about real events. For a complete letter with every required section, see our sample affidavit letter for a marriage case.

Each sample names the writer’s birth date and place, address and relationship, states how and when they met the couple, and gives specific events with dates and places. That is what the regulation asks for, and it is what makes an affidavit checkable.

If you lack joint documents: what to send instead

Many real couples have few joint records at first. One spouse may be abroad, may not be able to open a U.S. bank account or join a lease before getting a Social Security number, may live elsewhere for work, school or military service, or may come from a culture where couples keep finances separate. Separate records are not proof of fraud, but they leave a gap your file must fill. Start with a short signed statement from both spouses explaining why, then document the shared life you do have. Couples still at the fiance stage can see our list of K-1 proof of relationship examples, which covers long-distance evidence in depth.

Higher evidence bars that apply to some couples

Two situations raise the standard from “more likely than not” to “clear and convincing evidence.” The first is a marriage that took place while the beneficiary was in removal proceedings; the petitioner must ask in writing for the bona fide marriage exemption and file it with the I-130, unless the beneficiary has lived outside the United States for two years after the marriage. The second is a green card holder who got status through an earlier marriage and petitions for a new spouse within five years. In both cases, plan on a deeper file and expect an interview. If a case was already denied, see our explainer on challenging an I-485 denial over marriage evidence.

The Policy Manual also notes that failing to prove a bona fide marriage does not by itself mean USCIS has found fraud. A thin file usually draws a Request for Evidence or a Notice of Intent to Deny first, which gives you a chance to add what is missing. A finding that someone entered a marriage to evade immigration law is different: under INA 204(c) it bars approval of any later petition for that person.

The rules behind this checklist

Bona fide marriage evidence for the I-130 is governed by 8 CFR 204.2(a)(2) (marriage certificate, proof prior marriages ended, photos) and the evidence types in 8 CFR 204.2(a)(1)(iii)(B). USCIS explains how officers apply them in Policy Manual Volume 6, Part B, Chapter 6, most recently updated on October 17, 2025. Removal of conditions is governed by INA 216 and 8 CFR 216.4, with officer guidance in Policy Manual Volume 6, Part I, Chapter 3. Fees come from Form G-1055, edition dated October 7, 2026.
