1 Day Overstay On Non B Guidance in Thai visas, residency and work permits Posted March 25, 2013 Hi all, Appreciate some views on this. I've been on a continual non B for 9 years never had a bump in the road here. Only flight I managed to get for a visit home was on 1st April. Non B expires on 31st March. I am forwarding my documentation at home this time for another visa rather than an extention. Does anyone forsee any grief at Bangkok for being over and do I have to pay a fine before being summoned by immigration for depature? If it would involve some condescending gestapo like dance because of this at Suvarnabhumi and effect my application when sending to the consulate I'd rather just go down for a 7 day extention as I still have time? Many thanks for any help.
