How to get a Vietnamese visa in Bangkok: everything you need to know
Visitors to Vietnam from most countries are required to have a valid Vietnamese visa in their passport before arrival. This should be arranged in advance. If you are already traveling in Southeast Asia, the Vietnamese embassies in Bangkok or Phnom Penh are the quickest and most reliable places to secure a visa.
The Vietnamese embassy in Bangkok is especially efficient and rarely crowded. Simply fill out the one-page application form, submit your fee, and come back in two or three days to collect your passport. The embassy can issue one-month or three-month single or multiple-entry tourist visas.
The embassy of Vietnam in Bangkok is located just down the road from the US embassy at 83/1 Wireless Road, Lumphini, Pathumwan, Bangkok 10330, Thailand (near BTS Ploenchit Station).
Make sure that you have passport photos with you, as they are required to submit the application.
The embassy opens from 9:00-11:00 to submit visa applications, and I recommend getting there early.
The embassy is open for visa pickup from 14:00-17:00.
A one-month single-entry tourist visa (the most common visa type) costs 2400 THB for 4-day service, and 3000 THB for next-day service.
There is a new government e-visa website, but I have not used it yet. If you have successfully used the new Vietnamese e-visa, please let me know!
As of 2019, there are signs posted at the embassy informing visitors that the popular “visa upon arrival” program that is offered by a number of agencies in Vietnam is not endorsed by the Vietnamese government. While people do have success using these companies, I cannot recommend them.
