What Is a Marriage Affidavit?
A Marriage Affidavit (also called a “Letter of Support for Marriage”) is a written statement used in U.S. immigration cases to verify that a couple's marriage is real (bona fide). It’s often submitted during:
Marriage-based green card applications
Adjustment of status interviews (Form I-485)
Visa fraud investigations or RFEs (Requests for Evidence)
The affidavit is usually written by a third party (friend, family member, religious leader) who can confirm the authenticity of the marriage.
When Do You Need a Marriage Affidavit?
USCIS may request this affidavit when:
You're applying for a green card through marriage
You've received a Request for Evidence (RFE)
There is concern about the authenticity of the relationship
In some cases, the couple may also submit self-written affidavits to explain the relationship’s history and timeline.
What to Include in a Marriage Affidavit
A good affidavit should include:
Full name and address of the affiant (the person writing the affidavit)
Their relationship to the couple
Personal knowledge of the marriage (e.g. events attended, time spent together, conversations)
Specific examples proving the marriage is real
Date and signature of the affiant
