Vietnam has been open for tourism for seven countries with Thailand and the United States being two of them. I'm a US citizen currently living in Thailand. You will have to quarantine for 3 days but if you are a vaccinated then you can get in on a tourist visa.
I hear with Cambodia pretty much anyone can get in but Vietnam would be my top choice to leave the country for a visit.
one other question. Can I visit any country such as Vietnam or India or does it specifically have to be Cambodia? I mentioned Cambodia because that was the easiest country to get in without having to quarantine. Vietnam is only a 3-day quarantine which I can handle.
so I am in class for 3 hours a day and you tell me an additional 1 to 2 hours of studying after class is not enough. That's 5 hours a day total. Studying 8 hours a day is not realistic.
I came in under a tourist visa because I could not get an ED one unless I was in Thailand. Within 3 weeks of my arrival I signed up for class for a 1 year course. So tell me what I did wrong when you could not get an ED visa without being in the country first.
