show your passport

carry a passport

Often appears with verbs like 'show', 'carry', 'check', and adjectives like 'valid' or 'expired'. Distinguish from a visa: a passport proves identity and nationality, while a visa gives permission to enter.

💡a visa gives permission; a passport is the identity document.
❌My passport is overdue, so I need a new one.
✅My passport has expired, so I need a new one.
💡use 'expire' for documents, not 'overdue'.
