How long does the process take to get a teacers licence, and do I have to do it myself?

You need a school backing you up in order to get yourself a teacher’s license. If the school can’t do the paperwork then your own chances of doing it will be slim to non-existent. Many schools do not actually know how to get licenses and work permits for foreign teachers, or do not have a member of staff who has ever done it. In this case things can get very drawn out with the application being postponed indefinitely. If you’re the first or only foreigner in a school, good luck.

The actual process need not take a long time. The important thing is to get the teacher’s license because that will enable you to make your work permit application which is enough to extend your visa. When I process these, I consider the day the visa expires to be the deadline for getting the license in my hands. It can be done in a week. I aim for a month. If the paperwork is flawed you can just keep on waiting.
