Requirements for extending a visa

Hello all,

A friend of mine has come to Taichung in the hopes of finding employment as a teacher. Unfortunately, he has had a bit of a hard time with the schools that he thought he was going to wrok at. Now his visa is about to expire but it is an extendable one. Can he do anything to get it extended? I know a while back when I got my visa extended I had to show the Police Department, a document that the government was working on getting my Work Permit. The problem with my friend is that he is not employed at any schools so no one is trying to get his Work Permit processed. His current work permit expires in nine days is there anything he can do?

Thanks for any help.
