FYI. Went today to Krabi Immigration for 90 day report, done in less than 2 minutes. My friend needed an Extension of Stay for her Non-O, due to admitted to stay till 25 jun and flight on 1 Jul. I explained the officer, he directly told I can only give 7 days, I replied I know but she need only 6 and does not want to make a border run before 25 jun. He smiled and said I do not like to go to that border. Was little busy, handed over the passport and 1 picture, waited 1 hour before everything processed, than it came out her passport was full. He took passport to head of office, came back and just put the stamp as high up as possible on the page for endorsement. He told her, there is enough place for exit stamp, but next time change passport on time. Charged her 1900 Thb. Good service.
