I tried to get a 1 year extension of my O-A visa today at CW, Bangkok. My current extension expires November 19th. My new insurance policy was dated to start November 19th. The immigration officer told me I had to come back Nov 19th. I can come back early but I will lose whatever time on my current extension. All my other documents were OK. When I return my insurance policy has to start the day of my return to Immigration.
Sooooo . . . . I've asked Pacific Cross to change the date and I will give it another try this week. I have reasons to want to get this done earlier rather than later.
