My girlfriend and I are supposed to leave for Thailand tomorrow from the US. She is a valid US passport holder, but we didn't notice that Thailand has the rule about the passport needing to be valid for 6 months after entering the country. She was already able to check into the flight, and they may be checking during boarding again. But my main question is what are the odds we can get through Thai immigration? We can provide our itineraries, hotel confirmations, etc. if that will help, but will it? Thanks for any speedy advice.
