I recently visited the my immigration office for a 1 year extension (married to Thai wife). I got the usual "under consideration" stamp. I take this to mean that the extension is a pretty sure thing because if there was any problem the IO would have refused to send the paperwork on. In the collective knowledge of this group, is anyone aware of an extension being refused at this stage (i.e. while "under consideration)? Or is it just a rubber stamp exercise to allow time for the paperwork to go to the appropriate office and be scanned/entered onto the computer?
