Do you need a return or onward ticket to enter Vietnam (Nha Trang), and what to do if you're only flying one-way?

One traveler asked whether it's possible to quickly buy a return ticket on the spot and show it if immigration asks — looking for practical hacks for this situation.

Travelers discussed whether Vietnam immigration actually checks for a return ticket, and whether you can just make a booking (without paying) solely to show at the checkpoint.

Those planning to relocate to Nha Trang without a return ticket were advised not to worry in advance and to check with the community whether a return ticket is actually mandatory for long-term stays.
