Hello TVA folks again! US passport on an retirement visa that has a renewal date in Jan. Sorry to bother you all with a question regarding a border crossing at Mae Sae. My extension ends on the 12th of Jan. If I were to cross the border on the 12th and try to return with a 30 day entry on arrival, do I need to cancel my non-o before I do so at CM Immi? Or will it just be done automatically without needing to do so? I also have a mutliple-reentry permit. Thanks again for your help in these matters!
