A replacement passport changes the identity document used in your immigration file. Keep the old and new records connected while confirming the procedure needed to update your stay records.
Keep both passports accessible
Before surrendering or storing the old passport, make clear copies of its identity page, visa, latest entry, extension and re-entry records. Ask your passport issuer which document-retention rules apply. A copy is a reference, not a substitute for an original where immigration requires one.
Ask which records need updating
Explain whether you renewed the passport normally or replaced a lost or damaged one. Ask the handling immigration office about recording the new passport and any transfer or annotation procedure. Also ask how an existing re-entry permit, future reporting and an upcoming extension should be handled.
Prepare a cross-reference sheet
- Old and new passport numbers.
- Name and nationality as shown in each passport.
- Issue and expiry dates.
- Current permission-to-stay date.
- Relevant appointment and travel dates.
If there is a name change as well as a new passport, ask which supporting evidence is needed. Avoid treating it as a simple number update without explaining the change.
Coordinate with banking and travel records
Ask your bank about updating its identification record before requesting final financial evidence. Check upcoming airline booking details with the carrier. Keep each organisation’s instructions separate so an update in one system is not mistaken for an update in every system.
Frequently asked questions
Does a new passport automatically extend my stay?
No. Continue to manage the current immigration deadline unless the authority grants a new permission.
Can I discard the old passport after receiving the new one?
Keep it available while confirming the immigration procedure and evidence required for your case.
