⚠ If something goes wrong
Form I-363 lets a person who was admitted under the Amerasian law ask USCIS to make the sponsor keep their promise of support and to start legal custody. The request can be made by the beneficiary themselves or by the person who has legal custody of a child beneficiary.
The beneficiary of a P.L. 97‑359 Amerasian petition files the form, or any agency or individual (other than the sponsor) who has legal custody of a beneficiary under age 18.
The form collects the applicant’s statement, contact information, and certification in Part 4, interpreter details in Part 5, preparer details in Part 6, and any additional information in Part 7.
The filing address is posted on the USCIS website at www.uscis.gov/I-363; submit the form to the address listed there.
Complete the form by typing or printing legibly in black ink. Fill Part 4 with your statement, contact details, and sign and date it; if you used an interpreter, complete Part 5, and if another person prepared the request, complete Part 6. Attach legible photocopies of any required documents and, for foreign‑language items, include full English translations. Use Part 7 for any extra information, then mail the signed form to the address shown on the USCIS I‑363 webpage.
If the form lacks a required signature, USCIS rejects it as deficient, and it is not considered properly filed until accepted.
