Thanks Lloyd. Just for your info the school manager has also come back to me this evening and said I have to go to Chaeng Wattana because I live in Bkk. If she is wrong, which wouldn't surprise me, it would certainly make my life easier.
Was due to go tomorrow but been postponed anyway. My Non B expires September 5th that and the work permit is what I have. I'm not very good with the terminology....
"I have a work permit (the blue book) from Nonthaburi Ministry of Labour office and my Non B visa expires on September 5th." That is from the post I wasn't sure of the correct terminology that's why I posted on here because there are some very well informed and helpful people. This is the first time I have received an ignorant reply. I'm sorry I thought this group was to help people who needed assistance....
