Although Vietnam can also visa on arrival, but there are requirements, you have to get a qualified travel agency to give you approval, and the degree of trouble and time is the same as our direct visa. How to do that?
A passport valid for more than 6 months
2 inch white background photo
Go directly to the embassy when you're ready, no appointment required
Go to the embassy, pick up the visa application form and fill it out
Attach the photo and give it to the embassy staff along with your passport
He'll give you a receipt when you get it
Just take the receipt and get your passport when it's time
