What to Include in Your Marriage Green Card Cover Letter (AOS and CP)

USCIS does not require a cover letter. But immigration attorneys universally recommend one. A clear, numbered cover letter helps the officer locate every document in your packet, signals that you filed a complete package, and reduces the chance of a Request for Evidence (RFE).

What is a USCIS cover letter?

A USCIS cover letter is a one-page document you place on top of your application packet. It identifies who is filing (petitioner and beneficiary), what is being filed (the petition type and relevant forms), where the documents are going (the USCIS lockbox or NVC address), and most importantly, a numbered list of every document enclosed.

Think of it as the table of contents for your packet. When a USCIS officer opens your envelope, the cover letter is the first thing they see. A clear, organized letter tells them immediately that you know what you are doing and that your packet is complete.

Is a cover letter required for USCIS?

No. USCIS does not list a cover letter as a required document in the I-485 or I-130 instructions. You will not get an automatic rejection for omitting one.

That said, every experienced immigration attorney includes one, and for good reason. USCIS processes millions of applications. A disorganized packet with no cover letter is more likely to generate a Request for Evidence (RFE) because the officer has to hunt for each document rather than check it off a list. An RFE adds months to your case.

The cover letter costs you nothing and takes a few minutes. The upside is real. Include one.

What to include in an I-485 cover letter (Adjustment of Status)

For an AOS filing (whether you are filing I-130 and I-485 concurrently, filing I-485 standalone after I-130 approval, or filing I-485 as a K-1 entrant), your cover letter should contain these elements, in this order:

1. Your return address: the petitioner's name and U.S. mailing address. This is how USCIS will contact you if something goes wrong.
2. Today's date: written out in full (e.g., May 19, 2026).
3. The USCIS lockbox address: for most immediate-relative I-485 concurrent filings, this is: USCIS, P.O. Box 805887, Chicago, IL 60680-4120. Verify at uscis.gov/i-485 before you mail. Lockbox assignments change.
4. A Re: line identifies the filing type and both parties. Example: "Re: Concurrent Filing, Form I-130 / Form I-485 · Petitioner: Jane Smith · Beneficiary: Alex Smith."
5. A-Number (if applicable): include the beneficiary's Alien Registration Number if they have prior immigration history. Format: A-123 456 789.
6. A numbered document list: every document in the packet, in the order it appears. This is the single most important part of the letter.
7. A brief closing paragraph: one or two sentences requesting that USCIS process the petition and direct questions to the petitioner's address above.
8. Signatures from both petitioner and beneficiary: include printed name and role (Petitioner / Beneficiary & Applicant) below each signature line.

What to include in a Consular Processing cover letter

Consular processing (CP) involves submitting documents to the National Visa Center (NVC) before your case is forwarded to the U.S. Embassy or Consulate where the beneficiary's interview will take place. The cover letter for the NVC stage looks similar to the AOS letter, with a few differences:

• Address the letter to the NVC, not a USCIS lockbox: National Visa Center, 32 Rochester Avenue, Portsmouth, NH 03801-2909.
• Include the NVC Case Number: found in your NVC welcome letter. Format: NYC2024XXXXXX.
• List the beneficiary's current address abroad: the NVC uses this to identify which embassy or consulate to route the case to.
• Only the petitioner signs: the beneficiary is abroad and not a party to this stage of the submission.

Common cover letter mistakes to avoid

• Not listing every document. Every item in your packet should appear in the numbered list. If it is in the envelope, it should be on the cover letter.
• Using an outdated lockbox address. USCIS changes lockbox assignments. The Chicago P.O. Box is correct for most immediate-relative AOS concurrent filings as of May 2026, but verify at uscis.gov/i-485 before mailing.
• Mixing up AOS and CP details. The two letters go to different addresses and have different signature requirements. Using the wrong format can cause your packet to be mis-routed.
• Leaving template placeholders in. If you use a template, review it carefully before printing. A letter that still reads "[PETITIONER NAME]" tells the officer you did not proofread.
• Writing a personal narrative. The cover letter is a table of contents, not a love story. USCIS does not need to know how you met or why you got married here. Save the personal statement for your evidence of bona fide marriage.
• Forgetting to sign. The signatures at the bottom of the AOS cover letter (both petitioner and beneficiary) confirm that the enclosed documents are accurate. Do not skip them.
