I was thinking of a short 3 day holiday in Ho Chi Minh. I hear it's nice. Can I apply for the non-O based on being over 50 in Vietnam as well? I assume I need to go to the Thai embassy there? Can it be completed in the 3 days?
I also had a very difficult time finding a doctor to sign the form. After searching for a few days finally went to clinic that does tests for immigrants. It was pretty expensive. He wanted blood tests for most of them. He had to call the labs to even see if tests were available. It was the biggest hassle for me to get the VISA. The other issue i had was the doctor kept the original results and made me a copy. The thailand embassy said they needed the original. They took my application with condition i mail the original to them.I think part of the problem was doctors are fearful of lawsuits and didn't want to sign something they were not familiar with.
