Visa on arrival sounds casual. The fine print is not.
- Cash only. Stamping fees are often payable in crisp US dollars. Vietnam charges $25 or $50 at the airport. Card machines are not guaranteed.
- Onward ticket required. No proof of leaving, no entry.
- Airport only, in many cases. Vietnam's visa on arrival works at major international airports, not land borders. The e-visa covers 83 entry points instead.
- Passport validity: 6 months minimum, nearly everywhere.
- It is not available to every nationality at every border. The VOA list is per-passport.

Visa on arrival sounds easy until you meet the fine print: onward tickets, cash fees, and blank pages.
The move most experienced travelers make: get the e-visa instead. Same destinations, approved before departure, no airport queue, no cash scramble. Visa on arrival is a backup plan wearing a convenience costume.
