How to Prove Your Marriage is Real for USCIS

What “bona fide marriage” means in plain English

“Bona fide” is the official USCIS term for a real marriage: one entered for the purpose of sharing a life together. The legal question USCIS is asking is not how elaborate the wedding was or how long the couple has been together. The question is whether, at the moment of the marriage, both spouses intended to live as a married couple and not solely to obtain an immigration benefit.

The federal rule that lists the categories of evidence USCIS expects is at 8 CFR 204.2(a)(1)(iii)(B). USCIS officers also follow the agency’s internal Policy Manual chapter on spouses, which tells them to weigh every relevant fact and look at the marriage as a whole.

The takeaway: no single document proves a real marriage, and no single missing document disproves it. The picture across many items is what matters.

What “marriage fraud” means and why USCIS scrutinizes it

Marriage fraud is entering a marriage solely to gain an immigration benefit. It is a federal crime and a permanent ban on every future spouse-based green card filing for the immigrant spouse, even if a later marriage is real.

Two federal laws drive the consequences:

• The federal immigration law (the part of the Immigration and Nationality Act commonly cited as INA 204(c)) permanently bars approval of any future visa petition for an immigrant who previously entered, or attempted to enter, a marriage to evade the immigration laws. There is no waiver. The bar applies for life, regardless of any later legitimate marriage.
• A separate federal criminal law (8 U.S.C. 1325(c)) makes marriage fraud a federal crime. Anyone who “knowingly enters into a marriage for the purpose of evading any provision of the immigration laws” can be imprisoned for up to 5 years, fined up to $250,000, or both.

USCIS treats every marriage-based case as a potential fraud case at the screening stage, not because most are, but because the stakes of missing one are high. Officers are trained to look for patterns that real couples occasionally show too, which is why honest couples sometimes feel they are being treated as suspects. Strong evidence is the antidote.

How USCIS officers actually evaluate the evidence

USCIS officers use what they call a “totality of the circumstances” approach, meaning they look at the whole picture instead of any single document. The officer mentally weighs every item in the file together: the documents the U.S. spouse submitted with Form I-130 (the petition the U.S. citizen or green card holder files to start the case), the answers on Form I-485 (the green-card application the immigrant spouse files), what the couple says at the interview, and how the answers line up with the documents.

If USCIS wants to deny a case as fraud, the bar the agency has to clear is called “substantial and probative evidence.” In a 2019 ruling (Matter of P. Singh), the immigration appeals court that sets binding policy for USCIS officers defined this as “more than a preponderance of the evidence, but less than clear and convincing evidence.” In plain English: more than “more likely than not,” but less than “beyond reasonable doubt.” USCIS can rely on direct evidence, circumstantial evidence, or both, and circumstantial evidence alone can be enough.

What this means for an honest couple: the goal is to leave so little room for circumstantial doubt that the officer never has to think hard about the case. A clean packet with strong items in every category does that.

Tier 1: Joint financial evidence

Joint financial evidence is the single strongest category in the eyes of USCIS. It shows the couple has combined the part of life that most people guard most carefully: their money. Bank-issued statements come with dates and account-opening histories, so they are hard to manipulate.

Items to gather, in roughly descending order of weight:

• Joint federal tax returns filed as Married Filing Jointly, with IRS transcripts to confirm the filing
• Joint bank account statements (checking and savings) covering at least 6 to 12 months, ideally longer
• Joint credit card statements showing both names on the account
• Joint investment or brokerage account statements
• Beneficiary designations naming the spouse on retirement accounts (401(k), IRA, pension)
• Beneficiary designations on life insurance policies
• Joint auto loans or other major loans in both names
• Joint health insurance enrollment listing the spouse as a dependent
• Wire transfers, Venmo, Zelle, or check histories between spouses for shared expenses
• Wills, trusts, or powers of attorney listing the spouse

A note on account-opening dates. Officers can see when an account was opened. A 12-month-old joint account beats a 1-month-old one, but a 1-month-old joint account still beats no joint account. Open them now; do not pretend they are older than they are.

Tier 2: Joint living arrangement evidence

Joint living evidence shows the couple has built a shared home, not just a shared marriage certificate. A real shared address creates a paper trail across many independent companies, which is hard to fake all at once.

Items to gather:

• A joint lease or mortgage with both names
• A joint deed if either spouse owns the home
• Homeowner's or renter's insurance policy listing both names
• Utility bills (electric, gas, water, internet, phone) at the shared address; the strongest packets have at least one bill per month spread across several utilities, not the same single bill repeated
• Driver's licenses or state IDs showing the same address for both spouses
• Voter registration records showing the same address
• Mail received at the address by each spouse (USCIS receipt notices, IRS correspondence, bank statements, insurance statements)

If the immigrant spouse is not yet on the lease (a common pattern when the U.S. spouse owned the home or signed the lease before the wedding), add a letter from the landlord confirming the spouse lives there, plus mail in the spouse's name at that address. A statement from the landlord is not as strong as both names on the lease, but it is real evidence.

Tier 3: Joint life evidence

Joint life evidence covers the long-term planning side of marriage: the things couples do when they expect to be together for decades.

Items to gather:

• Birth certificates of children born to the couple, naming both as parents
• Adoption records showing the spouse as the second parent
• Health insurance enrollment listing the spouse as a dependent
• Auto insurance with both spouses listed as drivers on the same policy
• Joint phone plan or family wireless plan
• Joint gym membership or club membership
• Pet adoption or veterinary records listing both spouses
• Estate planning documents (wills, trusts, healthcare proxies) naming the spouse
• Emergency contact forms at work or school listing the spouse

Children together are extremely strong evidence, and USCIS treats them that way. A birth certificate naming both spouses as parents shifts the analysis significantly.

What officers look for at the green card interview

Every marriage-based green card case filed from inside the U.S. (the path called Adjustment of Status, or “AOS”) in 2026 includes a mandatory in-person interview at the local USCIS field office, with both spouses present. The interview confirms two things: that the marriage is real, and that the immigrant spouse is allowed by law to receive a green card.

What the officer is checking:

• Consistency between Form I-130 (the petition the U.S. spouse filed), Form I-485 (the green-card application the immigrant spouse filed), the documents in the file, and the answers given live
• A coherent story about how the couple met, how the relationship developed, the engagement, the wedding, and life since
• Knowledge of basic facts about each other and about daily life together
• A sense of integration: do you know each other's families, friends, routines, plans

Most marriage-based interviews last 20 to 45 minutes and end with the case approved on the spot or pending background-check completion. The officer asks both spouses together in most cases. Interviewing spouses separately during the first interview is one signal that the officer wants a closer look. For a fuller breakdown of the interview itself, see the interview prep guide.

When USCIS pushes back: requests for more evidence, denial warnings, second interviews, and fraud investigations

If the first interview leaves doubts, the officer has several next steps short of denying the case. Each one has a formal name (which we explain below), and each one is a chance to respond, not a denial.

A Stokes interview or an FDNS referral does not mean the case will be denied. It means the file did not yet make the case beyond the officer's doubt. Many couples in this situation choose to consult an immigration attorney before the second interview, and an attorney consultation can be a good idea when the stakes go up like this.
