Just adding a data point. Arrived in BKK, we had to fill out TDAC, the TDAC asked for leave date and airline flight, we picked a random one about 6 months from now and filled that in. When we went continued through immigration and got stamped no questions were asked, we simply gave them our A1 printed out visas and was stamped for 6 months.
Is there any additional forms, or reporting needed on our end if we plan on staying 6 months?
