Use accurate relationship and identity evidence required for the actual process and case stage.
Follow the relevant instructions
A record prepared for another purpose may not complete the update. Keep case references and the family history consistent without inventing a universal document list for every situation.
The official program terms as they read on the date of application, confirmation of the eligibility basis, records of the gift and processing fee paid through the official channel, and the applicant's identity, background and family documents. Follow the official process for questions rather than constructing a replacement receipt or assuming a discrepancy is irrelevant. Keep a source folder that preserves the official instructions as consulted, payment confirmations, identity and civil records, and every communication requesting further information. Retain the actual official instructions and receipts without describing a reimbursement promise as a completed government payment. The first review should preserve the official instructions, receipt and identity of the payer, then keep them separate from employment, investment or immigration-petition records. Any subsequent USCIS forms and supporting evidence should be prepared according to the official directions received. The exact documents depend on the process; do not rely on a universal private checklist or a screenshot that omits the notice’s conditions. Submit sensitive records through the authorized process, and verify official payment instructions independently of a forwarded private invoice.
