USCIS reviews marriage-based green card cases through a structured legal process that evaluates whether the marriage is genuine and not an attempt to evade immigration law. A U.S. citizen or permanent resident petitioner files Form I-130 (Petition for Alien Relative) to sponsor a foreign spouse, and the spouse then applies for permanent residence on Form I-485, with both forms reviewed by USCIS for marriage validity during the I-485 stage. The agency's central question is whether the petitioner can prove by a preponderance of evidence—roughly, a "more likely than not" standard—that the marriage is bona fide: genuine and entered in good faith, not primarily for immigration purposes. Federal law mandates that USCIS conduct "an investigation of the facts in each case" before approving or denying the petition, so this review is mandatory and thorough.

How USCIS Reviews Marriage-Based Cases
The process begins when the U.S. citizen or permanent resident spouse files an I-130 petition sponsoring the foreign spouse. The foreign spouse then files (or files concurrently with) Form I-485, the application to adjust status to permanent resident. Both forms travel together through USCIS, and the agency evaluates them during the I-485 stage to verify that the marriage is legal under state law and bona fide under immigration law. To support the I-130, the petitioner must submit the marriage certificate and evidence that all prior marriages by both spouses have ended—through divorce decree, annulment, or death certificate. However, these documents alone do not satisfy USCIS; the petition must also include evidence demonstrating the marriage is genuine.
What Evidence of a Genuine Marriage Looks Like
USCIS evaluates whether the couple can demonstrate a genuine, shared marital life. Examples include joint property ownership, a shared lease or mortgage, combined bank accounts, children born to both spouses, or written statements from friends, family members, or colleagues who can attest to knowing the couple as a married pair. USCIS applies a "preponderance of the evidence" standard, meaning the petitioner must prove the marriage is bona fide by a balance of probabilities. Importantly, USCIS focuses on the couple's intent at the time of marriage, not on whether the marriage will survive.
A divorce or separation after approval does not retroactively invalidate a marriage that was genuine when entered. Additionally, USCIS can deny a petition if the petitioner fails to meet the evidence standard for bona fide marriage, even without affirmatively proving fraud occurred..
When Interviews and Fraud Investigation Happen
Not every marriage-based case requires an in-person interview. USCIS conducts interviews when facts are inconsistent, documentary evidence of legal validity is insufficient, or facts raise doubt about the marriage's genuineness. The agency may begin with a joint interview of both spouses, then hold separate interviews if inconsistencies emerge or clarification is needed. If an officer detects fraud indicators—such as contradictions in the application, implausible timelines, or suspicious documents—the case is referred to USCIS's Fraud Detection and National Security (FDNS) directorate before final adjudication. FDNS may conduct a site visit to the address listed on the application to verify that the couple shares a residence and actually lives where they said.
Heightened Scrutiny: When USCIS Requires Stronger Proof
In specific circumstances, USCIS applies a stricter legal standard. If a spouse married while in removal or deportation proceedings, or if a permanent resident benefiting from a prior marriage petition remarries within five years, USCIS requires proof by "clear and convincing evidence" instead of preponderance. This higher standard—roughly equivalent to "beyond a reasonable doubt"—makes it substantially harder to demonstrate the marriage is genuine.
The Timeline from I-130 to Green Card
An approved I-130 petition is a significant milestone but not the final step. Even with an approved I-130, an immigration judge can deny adjustment of status if the beneficiary fails to establish that the marriage is bona fide. Final approval comes only when USCIS approves the I-485 application, which grants permanent resident status.
As of August 2024, the median processing time for a family-based Form I-485 filed separately from an I-130 was 9.4 months. Processing times vary by service center, so check current processing times on uscis.gov before filing. The timeframe can extend if USCIS requests additional evidence or schedules interviews.
Frequently Asked Questions
Can USCIS deny my petition without proving fraud?
Yes. USCIS can deny a petition if you fail to meet the preponderance-of-the-evidence standard for a bona fide marriage, regardless of whether fraud is shown.
Does an approved I-130 guarantee I'll get my green card?
No. An approved I-130 is a milestone, but final approval comes only when USCIS approves your I-485 application.
