Vietnam government currently issues 2 forms of visas. Regular visa (so called visa sticker) is a visa that is glued in a page of your passport. Loose-leaf visa (also called a paper visa) is a 5x7in-size visa card that carries your photo, name, date of birth, passport number, nationality, and the duration of time you are granted to stay in Vietnam. Both these visa forms are the same valid and same fee.
