Quick answer
What is USCIS Form I-363 used for?
If, after admission to the United States, the beneficiary of a petition for a Public Law 97-359 Amerasian requires enforcement of the guarantee of financial support and intent to petition for legal custody, which was executed by the beneficiary's sponsor, the beneficiary may file this form with USCIS.
I-363 enforces a specific Amerasian support undertaking
Form I-363 is a narrow enforcement request for a beneficiary admitted through the Public Law 97-359 Amerasian process when the sponsor’s earlier financial-support and legal-custody undertaking needs to be enforced. It is not a new affidavit of support, a general debt-collection form, or the petition used to obtain the original Amerasian classification.
Connect the request to the prior Form I-361 undertaking and the approved or admitted Amerasian case. Organize the sponsor identity, beneficiary record, promised support or custody arrangement, facts showing the alleged failure, and any communications or expenses that document the problem. If the case is based on a different family, humanitarian, or affidavit-of-support provision, verify the correct enforcement mechanism rather than relying on the similar financial-support wording.
