My O-A (long-stay) visa was issued (in New York) on 1 September, 2009 for entry before 31 August, 2010.
I entered Thailand on that visa on 14 October, 2009, and was stamped admitted until 13 October, 2010.
I went out of Thailand earlier this month and got back last Sunday ,May 23, 2010, and was stamped admitted until May 22, 2011.
I have plans for one or more trips outside of Thailand in the near future. As long as I reenter before 31 August, 2010, written on the visa issued in New York, I am assuming the stamps will be dated as in the last 2 times.
Two questions:
1. What should I do if foresee that I will not return before 31 August, 2010.
2. My next 90-day report is due on 7 July, 2010. May I assume that every time I renter, my 90 day reporting date is automatically reset? That is even if I do not leave Thailand my next reporting date will be 90 days from May 23, 2010.
Thanks for your help.
