You'll be fined at the rate of 200 kwai a day for each day you are overdue past a grace period of ten days. In addition, they may give you a temporary visa valid for five days and tell you to leave the country. Being American increases your likelihood of being kicked out; however, you can start the process over once you get back home. This time, however, if I were you I would make sure you are being hired by a legally registered entity, be it a private school or a public one.

If you're still employed by a school that has not taken care of your visa problem, chances are you are illegally employed by said school. Be careful; more trouble could come your way if that's the case. They may be breaking the law by employing you - you may be breaking the law by working for them.

There are agencies that answer questions for you - people who are authorized by the various embassies to do so, but you will have to get online to find their phone numbers.

The PSB may try to fine you for each day you are overdue if they think you are unaware of the grace period. Humbly yet assertively make them aware that you know the law but that due to your injury you were unable to comply. It may be wise to have a legal representative a quick phone call away. Be sure to have your medical records and your doctor's phone number so that it can be verified that you were actually in the hospital.

Hope it works out for you.
