What to do if you have passport or exit stamp problems when departing Nha Trang (Cam Ranh Airport)?

A border officer mistakenly stamped an exit date 5 days earlier than intended; the hotel refused check-in because of this stamp, forcing a rush back to the airport to sort it out with border officials in order to make the flight.

There have been cases where the immigration queue took a couple of hours — by the time travelers cleared it, their luggage had already been circling on the baggage belt for a while, so build in extra buffer time.

Before a flight, a passport was lost; an emergency replacement was arranged through Russia's Gosuslugi portal with expedited processing in 7 days instead of the usual month (some offices report 11-day turnaround); flight tickets had to be rebooked with a penalty fee, and additional embassy clearance was required — the advice is to start the replacement process immediately if this happens.
