Help! The Police Are After Me!

So, I just got back from Thailand a couple days ago and my neighbor came over to tell me that the police had been looking for me while I was gone! He said they came by a few times! Apparently they needed something for my registration, b/c here everyone has to register your exact location with the police and give them copies of all sorts of stuff. Well, I guess I forgot something. Then later that same day, a lady from my apartment called me and, after a friend's translation, I found out that the police had called her looking for me! They told her my visa had expired and I either needed to take them a copy of my new one or leave the country! It was crazy. So I tried to go today so they didn't get more upset, only to find out that they need a copy of my apartment contract and their copy machine is broken so I have to find somewhere to do it myself! Good grief. I knew the police kept close tabs on foreigners, but this is much more than I've ever experienced! My friend said they'd also been to his house asking all sorts of questions... Welcome to Asia! : )
