Check your Form I-539A for errors before you file

Adds a co-applicant — a spouse or an unmarried child under 21 — to a Form I-539 application to extend or change nonimmigrant status. A single blank field or wrong-edition page gets the whole package returned, and since 07/10/2026 an invalid signature can be denied outright — and I-539A carries no USCIS fee of its own, so what a rejection costs is the delay on everything it was filed with. Here is exactly what to verify on your completed I-539A before it goes to USCIS.

How do I check my I-539A for errors?

1. Confirm you have the current edition

USCIS accepts only the current edition of I-539A — filing a superseded version is an automatic rejection. The current edition is dated 08/28/24; the date is printed at the bottom of every page. All pages must come from the same edition. Download a fresh copy from uscis.gov right before you file.

USCIS is not accepting the 09/15/26 edition. A court order of Sept. 14, 2026 postponed the rule that introduced it (Presidents’ Alliance on Higher Education and Immigration, et al., v. DHS, 26-cv-13799, D. Mass.), and USCIS continues to accept the edition shown above.

2. Verify every signature block

Unsigned or wrongly-signed forms are rejected — or, under the signature rule effective July 10, 2026, denied outright with the filing fee kept and no chance to fix it. A typed name, a cursive or script font, a stamp, or a digital e-signature (such as DocuSign) is not a valid signature on a paper filing; only a handwritten ink signature — or a scan, photocopy, or fax of one — is accepted. An electronic signature counts only when it is captured through a USCIS online account during online filing. I-539A has 4 signature blocks to check:

3. Make sure no required section is incomplete

Leaving required fields blank (instead of writing “N/A” or “None”) is one of USCIS's most common rejection reasons. On I-539A, pay special attention to:

• Part 1, Items 1: The full name of the person filing the Form I-539 this supplement attaches to — this is the ONLY item in Part 1, and it is not about you
• Part 2, Items 1 – 5: The co-applicant’s own name, date of birth, country of birth, country of citizenship or nationality, and U.S. Social Security Number (if any)
• Part 2, Items 6 – 10: The co-applicant’s A-Number (if any), passport or travel document number and country of issuance, and USCIS Online Account Number (if any)
• Part 2, Items —: Most recent entry into the United States: date of arrival, Form I-94 number, and current status with its expiration date
• Part 2, Items 15.a: The status being requested for this co-applicant — it must match what the principal is requesting on the Form I-539
• Part 3, Items —: Additional information about the co-applicant, including the eligibility and public-safety questions

4. Check every date — format and consistency

Dates must be written mm/dd/yyyy and must agree with your supporting documents and any other forms in the package. The date fields that most often cause problems on I-539A:

• Part 2 — date of arrival and the I-94 expiration date — These must match the co-applicant’s own I-94, not the principal’s, and the application must be filed before that expiration.
• Part 2, Item 2 — date of birth — A child co-applicant must be unmarried and under 21; a date of birth that puts them over 21 changes their eligibility to be included at all.

5. Re-check the known I-539A filing problems

From USCIS's own instructions and guidance, these are the specific problems to rule out on I-539A. Some get a filing rejected at intake; others surface later as a Request for Evidence or a denial:

• One Form I-539A used for more than one co-applicant — each co-applicant needs their own
• A Form I-539A submitted for the person already named on the Form I-539 — the form states not to
• Not signed by the co-applicant (or by a parent or guardian for a child) (a typed, script-font, stamped, or digital/e-signature is invalid where an ink signature is required; as of 07/10/2026 this is a denial with the fee kept, not merely a rejection)
• Filed after the co-applicant’s authorized stay expired
• Filed on an edition that does not match the Form I-539 it attaches to

What happens if my I-539A is rejected?

USCIS returns the entire package unprocessed — and because I-539A travels with other forms, everything filed alongside it comes back too. You correct the error and refile the whole package, losing weeks or months. That is why a careful pre-filing check is the cheapest step in the whole process.
