yes I already got a 30 day extension at a local immigration office and it expires the day after tomorrow. I just need to leave Thailand and re-enter and I'm pressed for time, hence considering the nearby Mae Sot/Myawaddy border, but I"m getting very little information about doing such runs at this border crossing. Spent a lot of time googling and it seems people have done this border visa run before but it was a while ago and my co-worker seems adamant that it cannot be done. Must already have a Myanmar visa or some other conditions, yet I've seen online some accounts of easily getting a day pass into Myanmar for 500 baht to do this. Very confusing.
