I know someone has has this about a bank robbery charge in their past and getting a visa of some sort.

I want to get a retirement visa. I first need to get a non immigrant visa from outside of thailand and it seems like I can do this from any country. Is this true? Also, I grew ganga professionally and was busted for it and served time in a federal prison. no guns involved and I was arrested in 1995 and have a totally clean record since then. the problem is that I show up on Interpol as a trafficker. I want to know if anyone has any idea on the depth of background checking that goes on and if anyone has any idea about being totally straight for over 20 years makes a difference. And if I apply for a non immigrant visa, and can do it in any country around this neighborhood, which would be the best considering my situation. I have all the other requirements met with the ability to get money into a thai bank, or use a combination of retirement money (social security) and bank money. Or I could just do the 800,000 B, no problem. Any advice is greatly appreciated in advance. JB
