Spousal I-130 and adjustment of status

I-130 affidavit sample for a marriage petition

Last updated 2026-10-01

For a spousal I-130, the USCIS instructions list affidavits from third parties with personal knowledge of the marriage as optional evidence of a bona fide marriage. Each should contain the writer’s full name and address, date and place of birth, and complete details explaining how they know about the marriage. At the I-130 stage, the best letters cover how the relationship began and grew.

What the I-130 instructions say

In the section for petitions filed for a spouse, the Form I-130 instructions say that in addition to the required documents you “should submit one or more” types of documentation that may prove a bona fide marriage. Item 5 on that list is affidavits sworn to or affirmed by third parties having personal knowledge of the bona fides of the marital relationship. Each affidavit must contain:

The other items on the same list — joint property, a joint lease, combined finances, children’s birth certificates — carry more weight. Use affidavits alongside them, not instead of them.

AFFIDAVIT OF MARCUS BELL IN SUPPORT OF FORM I-130 Petitioner: Laura Chen · Beneficiary: Tomás Alvarez

Full name: Marcus Anthony Bell Address: 3120 Westheimer Road, Apt 507, Houston, TX 77098 Date of birth: August 30, 1991 Place of birth: Atlanta, Georgia Relationship: Friend of both; introduced the couple Phone: (713) 555-0127

I am a high-school chemistry teacher in Houston. I have known Laura Chen since 2016, when we started teaching at the same school. I have known Tomás Alvarez since 2020, when he joined my recreational soccer team.

I introduced them. On November 5, 2022, I hosted a birthday party at my apartment and invited both of them; they talked on my balcony most of the night. Two weeks later Laura told me they had gone on a first date to the Museum of Fine Arts.

After that I saw them together regularly. Tomás started bringing Laura to our Sunday soccer games in early 2023, and she became the team’s unofficial photographer. I spent Thanksgiving 2023 with them at Laura’s parents’ house in Sugar Land, where Tomás cooked a turkey for the first time with Laura’s father supervising.

In July 2024 Tomás told me he planned to propose and asked me to help him get Laura to Hermann Park at sunset without her suspecting. I did. I attended their wedding on March 22, 2025, at St. Anne’s Church, and I gave the second reading during the ceremony.

Since the wedding they have lived together in an apartment in the Heights, where I have had dinner with them several times. Based on everything I have seen over almost three years, I know their relationship is real.

I declare under penalty of perjury that the foregoing is true and correct. Executed on ______________ (date). ______________________________ Marcus Bell

Why it works

Who makes a good I-130 affidavit writer?

Pick writers whose letters will describe different parts of your story. If three friends all describe the same wedding, the officer learns about one day; if one describes how you met, one your wedding and one your shared home, the officer sees a relationship.

Filing tips

Frequently asked questions

Are affidavits required for an I-130?

No. The instructions say you should submit one or more types of evidence of a bona fide marriage; affidavits are one option on that list.

How many I-130 affidavits should I include?

There is no set number for I-130. Two to four specific letters from different people is a common, reasonable package.

Can the petitioner or beneficiary write their own affidavit?

The affidavits described in the instructions are from third parties. Your own statement is a different document; ask an attorney if you think you need one.

Do I-130 affidavits need to be notarized?

Not necessarily. A statement signed under penalty of perjury under 28 U.S.C. § 1746 is a common alternative. See how to notarize an affidavit.
