Insufficient evidence of a bona fide marriage is one of the leading causes of Requests for Evidence in family-based green card cases. A marriage certificate proves you got married — it doesn't prove you have a real life together. Here's exactly what USCIS looks for, organized by evidence category.
Marriage fraud — entering into a marriage solely for immigration benefits, without any genuine relationship — is a federal crime under 8 U.S.C. § 1325(c). Because of this, USCIS is required to evaluate whether every marriage-based petition represents a genuine relationship entered into in good faith by both parties.
This doesn't mean USCIS assumes you're committing fraud. It means they need objective evidence — not just your word — that the marriage is real. The standard is that a marriage is bona fide if it was entered into in good faith with the intent to establish a life together, regardless of whether it later succeeds or fails.
A marriage certificate is necessary but not sufficient. It proves a legal marriage occurred. It does not address whether the people in that marriage have a genuine shared life. USCIS needs evidence of the latter.
Documents showing you share finances are among the most persuasive evidence of a genuine marriage. They demonstrate ongoing, practical commitment that goes beyond a ceremony.
Documents showing you live at the same address carry significant weight, particularly when they are independent of each other — meaning each spouse appears on a document independently, not just as a second name added to something the other spouse already had.
Photographs are expected in marriage-based green card applications, but on their own they are not sufficient. They supplement other evidence. What makes photographs more persuasive: showing a timeline across different times and places, including the wedding and candid everyday moments, showing both spouses with each other's family members, and including identifying context (recognizable locations, other people, dated events).
Organize photos chronologically and include brief captions identifying who is in the photo, where it was taken, and approximately when. Print them clearly — do not submit blurry or very small images.
Documents where you've named your spouse in a legal or medical context demonstrate ongoing commitment and practical treatment of the marriage as a real partnership.
Records of communication between spouses are most useful in long-distance relationships or cases where couples were separated for part of their relationship. They can demonstrate the ongoing nature of the relationship during periods of physical separation.
Written statements from people who know you as a couple can support your application. Affidavits are useful but should supplement objective evidence, not replace it. An affidavit is a signed, sworn statement from someone who has personal knowledge of your relationship — a family member, friend, or neighbor who has observed your life together.
Each affidavit should include the affiant's full name and address, how they know the couple and for how long, specific examples of times they observed the couple together, and a statement that the information is true to the best of their knowledge. Generic affidavits that simply state "I know this couple and believe their marriage is genuine" carry limited weight.
Long-distance marriages. If you and your spouse have lived in different countries or cities for significant portions of your marriage, you need evidence that explains why (work, visa restrictions, family obligations) and evidence that the relationship continued during the separation — communication records, records of visits, evidence of financial support across the distance.
Short courtship or recent marriage. USCIS may look more carefully at cases where the marriage is very recent or the relationship was short before marriage. This doesn't disqualify you, but including strong objective evidence of genuine commitment and a detailed timeline of the relationship helps address this scrutiny.
Large age differences. A significant age difference between spouses is not disqualifying, but it may prompt additional scrutiny. Strong relationship evidence and documentation of how the couple met and developed their relationship can address this.
Prior immigration-related marriage. If either spouse was previously in an immigration case involving a marriage petition, be prepared for additional scrutiny and consider consulting an immigration attorney.
There is no minimum number of documents USCIS requires. The standard is whether the totality of the evidence submitted establishes that the marriage is genuine. A common practical guideline among immigration practitioners: aim for at least two strong pieces of evidence from Category 1 (joint financials or shared residence), supplemented by a range of supporting evidence from other categories.
More evidence is almost always better than less — within reason. A well-organized package with 20–30 pieces of relevant evidence is far more persuasive than a thin package with 5 items, even if each of the 5 items is technically sufficient on its own.
When in doubt about whether a specific document is worth including: if it genuinely shows something about your shared life together, include it. The practical cost of including extra evidence is organizing it. The cost of not including enough evidence is an RFE or denial.
FormGuard checks your I-130 and I-485 for the errors and missing fields that most often trigger RFEs in marriage-based green card cases.
Check my forms →No. A marriage certificate proves a legal marriage occurred. It does not establish that the marriage is bona fide — that it was entered into in good faith with the intent to establish a genuine life together. USCIS requires evidence of a real, ongoing relationship: joint finances, shared residence, photos over time, and other objective documentation of a shared life.
If you are early in your marriage or have not yet set up joint accounts, focus on the evidence you do have: documentation of the same address, photos, affidavits, communication records, and any other objective evidence of your shared life. It is also worth explaining in a cover letter why certain types of joint documentation don't yet exist. If you have time before filing, opening a joint account and having a few months of statements before you file strengthens your application materially.
Long-distance marriages require additional documentation. Include evidence of communication (phone records, message history), evidence of visits (travel records, photos together in different locations, boarding passes or passport stamps), evidence of financial support (wire transfers, bank records), and a clear explanation of why you've been living separately. An immigration attorney can help structure the evidence package for a long-distance marriage case.
