I read on your site that te processing time for the vis is 6 working days during that period you will keep my passport. May I bring to your attention following strict enforcement by the Thai immigration:
1. By law, all tourists and expats nationwide are required to carry their original passports with them at all times. There is no exception to this.Failure to carry your original passport may result in a 2,000 THB fine. The reason behind this is that Immigration needs to keep track of overstayers and foreign criminals who may be staying illegally in the country.
