Residence documents such as leases, tax filings, or permanent resident cards describe where a person lives, which can matter for identity and history questions. They do not answer the classification or availability question. Supporting documents are filed with Form I-140G through the official portal after USCIS issues instructions, so follow that request rather than a self-assembled list.
Assemble a complete personal history
People who have lived in more than one country accumulate records in several places: prior visas, entry stamps, residence permits, and refusals or withdrawals.

Hidden history discovered later is worse than difficult history disclosed early.
