Just wondering if anyone can help. My 3 month Non Immigrant B visa expires on the 30th March. 2 weeks ago I went to immigration to extend it by 1 year but was denied as my company supplied the incorrect documents. I'm now going to immigration to get a 7 day extension. I was just wondering, if my company doesn't get the correct documentation in the next 7 days can I travel to another Thai Embassy say in Singapore/Malaysia and apply for another 3 month Non Immigrant B Visa?
