Hi - I have recently married my Thai girlfriend of 2 years, and I want to change my visa status from the current O-A visa that I on, to a "Support Thai Wife" visa.

Can anyone tell me if it is possible to change visa types in Thailand, or if I have to travel outside Thailand and re-enter Thailand on a different visa type, and, if I have to leave Thailand to effect a change of visa type, do I have to go back to my home country, or can it be a country close by?

I am aware of the Thai Immigration requirements I have to meet to qualify for the "Support Thai Wife" visa, other than the question I have raised above. My current O-A visa expires at the end of April this year.
