What evidence is needed for a K-1 visa?

On Behalf of | May 17, 2026 | Family Immigration |

When filing a petition to obtain a K-1 nonimmigrant visa for your fiancé(e), also called a fiancé(e) visa, you are required to submit supporting documents. The U.S. Citizenship and Immigration Services (USCIS) needs these documents to prove citizenship and relationship validity.

Here is what to submit when filing your application:

Evidence of citizenship

You are eligible to bring your fiancé(e) to the country if you are a U.S citizen. The documents used to prove citizenship are a copy of a U.S. birth certificate, an unexpired U.S. passport, a copy of a certificate of citizenship/naturalization, a copy of a Consular Report of Birth Abroad (CRBA) or an original statement from a US consular officer verifying citizenship.

Evidence of relationship validity

You and your fiancé(e) must have a bona fide relationship. To prove your relationship is real, you must submit evidence of an in-person meeting at least once within the two years before filing the petition. This can be passport stamps, flight tickets or time-stamped photos in different locations. 

You can request a waiver for this requirement if you can show that meeting in person would cause extreme hardship to you or would violate strict, long-established customs of your fiancé(e)’s culture or social practice.

Furthermore, you need to show that both you and your fiancé(e) are free to marry. So, if any of you were previously married, submit proof that the marriage was legally terminated by divorce, death or annulment.

Other documents to prove relationship validity include evidence that you are actively preparing for a ceremony within 90 days of your fiancé(e) entering the U.S., communication records (call logs, messages, emails, etc.) and statements from loved ones.

You are eligible to apply for a fiancé(e) visa if you can prove citizenship and that your relationship is genuine. Learn more about the process to make informed decisions and help your fiancé(e) enter the country.
