good for you. I didn't say ANYTHING about U.S. embassy so strike 1. Didn't say ANYTHIBG about confirmation of pension so strike 2. You absolutely have an attitude issue so strike 3.
If you are 50 yrs old, go with the non AO visa. No need for money in their bank. Use the Thai embassy near you for visa. We sent all papers and passports, got approved in two weeks from downunder.
