If you are a foreigner, you have to fill out forms at 9am the first morning. So if you have a connection flight that morning like we did, and wont be there to fill out forms, they will kick you out and refund your money. So at 1030pm we had no hotel and went back to airport to try to sleep on the bench, There is no info about this on the website. Had google translate to communicate which still makes for limited communication
