I am an American in Thailand on a tourist visa. The visa is stamped s for number of entry but has not amount of time on it. I assume it is for 60 days from what the embassy web page stated and I want to go to Cambodia for a few days. I'm concerned that I have a single entry visa and if I leave the country I can't get back in. I am scheduled to leave Thailand at the end of July though my return date could be pushed back because I bought an open ended ticket. Would it be best for me to wait until the end of July to go to Cambodia and renew my visa at that time in case I want to stay longer? If I wanted to go outside of Thailand now could I get back in and at what cost.
Thanks for your time.
