What Evidence Does USCIS Require to Prove a Bona Fide Marriage for a Green Card?

August 18, 2026

Getting married is one of life’s most meaningful milestones. But when your relationship spans national borders, and a green card is one of the requirements for starting your life together, USCIS needs more than a marriage certificate as proof. The agency must be satisfied that your marriage is bona fide, with a genuine intent to build a life together. Multiple forms of evidence can be used to prove this, including:

• Joint financial records
• Shared residency documentation
• Evidence of the relationship’s history
• Affidavits from friends and family

Officers usually also conduct an interview to verify the marriage’s authenticity before approving a green card petition.

At Zaveri Law Firm, we have experience guiding couples through this entire process. Our founder, Prerak A. Zaveri, Esq., has dedicated his practice to immigration law, and our team understands what USCIS officers look for when evaluating spousal petitions. Here is what you need to know to help prove that your marriage is genuine.

What Does USCIS Mean by a “Bona Fide Marriage”?

According to the USCIS Policy Manual, a bona fide marriage is one where both parties entered into the relationship in good faith, not primarily to circumvent U.S. immigration laws. USCIS evaluates whether the couple genuinely intended to establish a life together at the time of the marriage. A legally valid ceremony alone is not sufficient.

What Evidence Does USCIS Use to Prove a Marriage Is Bona Fide?

Joint Financial and Residential Documentation

One of the strongest categories of evidence is shared financial and residential ties. This can look like:

• Joint bank account statements showing commingled finances
• Joint lease agreements or mortgage documents listing both spouses
• Joint ownership of property, such as a vehicle or real estate

The more documentation you have showing that you and your spouse share a financial life, the stronger your petition. Couples who have been together longer typically have more of this evidence available, but even newly married couples should start building this paper trail immediately.

Photographs and Relationship History Evidence

USCIS officers want to see the full arc of your relationship. Photographs from different stages of your relationship, including dating, engagement, the wedding, and life after, help paint a clear picture. Strong supporting evidence can also include:

• Travel records showing when and where you spent time together
• Communications such as emails or messages (printed and organized)
• Evidence of shared social events, family gatherings, or holidays
• Records of prior visits, if the couple was long-distance before marriage

Do not underestimate this category. A well-organized visual and historical record of your relationship leading into your marriage can speak volumes.

Affidavits from Friends and Family

USCIS also accepts written statements from people who know the couple personally. Affidavits from third parties with direct personal knowledge of the relationship can be recognized as evidence of a bona fide marriage. Each affidavit must include the full name, address, and date and place of birth of the person submitting it, along with a detailed explanation of how they know the couple and what they have personally observed of the relationship.

Interview Preparation and Potential Red Flags

USCIS has the authority to interview both the petitioner and the beneficiary. Interviews are often done with both spouses together, but they may be separated in some cases, such as if fraud is suspected. During a separate interview, officers may ask detailed questions about daily routines, home life, family members, and shared experiences. Inconsistent answers can raise serious doubts about the legitimacy of the marriage even when the relationship is genuine.

Common red flags that USCIS watches for include a very brief courtship, large age gaps without explanatory context, no shared address, and prior immigration violations. Having an experienced immigration attorney prepare you for the interview process significantly reduces the risk of unnecessary complications.

You Do Not Need to Approach This Alone

Assembling a complete and compelling bona fide marriage package takes diligence, organization, and legal insight. Missing documentation or poorly drafted affidavits can delay your petition or even result in a denial, so proper preparation is key.
