Hi all. "Everything else" question: on obtaining tourist visa to Vietnam. I’m American, traveling from BKK to Vietnam as a tourist in a couple of weeks. Has anyone used one of those agents you find online offering a “letter” to be presented at the airport in Vietnam? If so, can you recommend one? They look like scams.

I went to the Vietnam embassy in BKK to apply for the tourist visa & they said you need an “approval letter” issued by the immigration dept. of Vietnam. This requirement does NOT appear on the Vietnam embassy Thailand’s website. In fact, their site warns to be wary of “fake websites.” Thanks for any advice!
