Submit the online application and processing fee, then follow USCIS’s email instructions for a myUSCIS account, Form I-140G and supporting documents. Make the gift only after successful vetting, and use the current agency instructions for the later immigrant-visa or adjustment documents.
Vetting documents first, adjustment documents second
The official page directs an applicant to submit the online Gold Card application and nonrefundable processing fee. USCIS then emails instructions to create a myUSCIS account and complete Form I-140G with supporting documents; the page does not publish a fixed universal document list and states that USCIS or the Department of State may request additional information. After successful vetting, the applicant submits the gift using the payment instructions then provided.
The later immigrant-visa or adjustment stage uses the forms, relationship records, medical examination and fees prescribed by the responsible agency for each applicant. The family should preserve the architect’s L-1B approvals and I-94 records and the dependants’ L-2 records so they can document current status while the process runs. Because program mechanics can change, the official page and agency instructions should be checked again before submission or payment.
