Hi, I was recently approved for the 6 Month tourist e visa with multiple entry in the US Thai consulate. I will be traveling to Thailand with this visa in the near future. My on fowad ticket is for Cambodia within the first 30 days, but I have plans of staying 90 days in Thailand and then return to Thailand again with this same visa. So I plan to either change the date of this flight to Cambodia or just buy another one later. My question is since my on foward ticket is for a date that is within the first 30 days, will they only stamp me for 30 days when I arrive to Thailand or will they stamp me for the 60 days? Also I read that I can extend the 60 days to 90 electronically while in Thailand, if I decide to use this service, how soon can I extend the 60 day stamp to 90 days? Thank you.
