Who qualifies

Spouses and unmarried children under 21 who want the same nonimmigrant status extension or change as the primary Form I-539 applicant.

The step-by-step roadmap

  1. 1

    Identify Eligible Dependents

    Prepare a separate Form I-539A for each co-applicant spouse or child included with the primary filer.

    Watch out: Each dependent requires their own Form I-539A; do not combine multiple people on one form.
    Common rejection reason: Filing for a relative who does not qualify as an eligible dependent under the visa category.
  2. 2

    Gather Co-Applicant Records

    Collect lawful entry records, valid passport details, and proof of relationship to the primary applicant.

    Watch out: Passports must remain valid for the requested stay duration.
    Common rejection reason: Missing or expired I-94 arrival record details.
  3. 3

    Sign and Date the Form

    Have each co-applicant sign their own supplement. A parent or guardian must sign for children under 14.

    Watch out: Every applicant aged 14 or older must physically or electronically sign their own form.
    Common rejection reason: Missing signature from a co-applicant aged 14 or older.
  4. 4

    Submit with Primary Form I-539

    Bundle all completed Form I-539A supplements directly with the main Form I-539 filing package.

    Watch out: Do not submit Form I-539A as a standalone filing; USCIS will reject it.
    Common rejection reason: Filing Form I-539A separately without the parent Form I-539 package.

Documents you'll need

  • Proof of Relationship

    Official marriage certificate for a spouse or birth certificate for each child, with certified English translation if needed.

    Note: Must clearly establish familial tie to primary applicant.

  • Form I-94 and Passport Copy

    Most recent electronic Form I-94 printout and copy of biographical passport page for the co-applicant.

    Note: Shows current nonimmigrant status and authorized stay.

  • Current Visa Page

    Copy of the U.S. visa stamp used by the co-applicant to enter the United States.

    Note: Required to confirm entry classification.
