Do I need a photo and if so, what is its size?

Yes, you do. However, photos are required upon arrival Vietnam’s airports only, so please remember to bring at least 2 photos of standard passport size (04*06 cm).

Note: If you do not have time to prepare those photos before your departure, you can also get them taken at a Vietnamese airport for 2 USD or less per photo.
