What documents can help verify someone's immigration or residency claims without violating privacy?

Direct answer
The safest evidence comes from the destination country’s consent-based official verification service, not a complete passport scan or access to an online account. In the United Kingdom, a status holder can voluntarily generate a time-limited share code and provide a date of birth so another person can view limited immigration-status information. Other countries use different digital records, residence cards or official letters. Documents should be checked with the issuing authority, with sensitive numbers masked when unnecessary. Status, expiry, work rights and eligibility to sponsor a spouse are separate questions.
