Start with proof of birth, parent-child relationship and marital status, plus any petition, decision and visa-availability dates relevant to CSPA. Disability records do not replace those eligibility facts.
Prepare a complete, specific inquiry
Ask which additional records are actually needed for the particular legal or accommodation question. Keep medical or care information directed to that purpose, rather than presenting it as proof that an age exception exists. Record gaps in the immigration chronology so the age assessment is based on dates, not assumptions.
Organize two files. The family file should contain birth certificates, parent-child and marriage evidence, passports, marital-status records, prior petitions, notices, admission history, and the dates needed for any CSPA analysis. A common mistake is using medical material to replace age or relationship proof; keep it only for an accommodation inquiry. The principal file must establish whichever EB-1 or EB-2 basis applies; Gold Card does not use EB-5. Preserve the official process record in order: an online filing accompanied first by DHS's nonrefundable US$15,000 processing fee; cleared payment; USCIS's I-140G prompt; subsequent vetting; and, only when vetting ends, the request for a US$1 million United States gift. Re-check official directions before transferring funds.
Hypothetical example: A Tecumseh cabinetry-workshop owner asks whether an adult child's care assessment proves inclusion, but cannot locate a petition notice. The household requests the missing notice, builds a dated case table, and supplies relationship records. Sensitive clinical documents remain outside the age analysis unless specifically requested for another purpose. The parent separately gathers EB-classification evidence and does not let an incomplete family chronology trigger premature payment.
