Follow the official application and Form I-140G instructions in effect when filing. The current sequence starts with the online application and DHS processing fee, followed by USCIS instructions for Form I-140G and supporting documents; identity, civil, admissibility, medical and visa documents may also be required. The gift is made only when instructed after successful vetting.
Follow the I-140G and official payment sequence
The current official page directs an applicant to submit the online application and non-refundable DHS processing fee first. After that payment settles, USCIS sends instructions to create an online account and complete Form I-140G with the supporting documents requested through the portal. Hypothetical example: a retired Lake Country applicant should prepare accurate identity, civil, immigration and business-background records and then answer the actual I-140G requests rather than assume that a conventional awards-and-publications file is mandatory.
Immigrant visa processing may separately require passports, civil records, police certificates and a medical examination. After successful vetting, the applicant receives instructions for the gift; it should not be wired earlier. Keep the official receipts and instructions, and re-check the programme page because the form, requested evidence and payment steps may change.
