Okay if you get a school and you have a non b visa for those at the southern part of Thailand when you have your work permit and you go to to the immigration for a one year extension you pay 1900 baht they stamp only two weeks on your passport they say that they are doing that for clarification then after two weeks there's a specific date they write to you that you should report to the immigration I might miss that date by one day now that's where the issue is...and I don't have a one year extension yet am still under consideration
