Work with TARC

Hello everybody.

I have a Taiwan residence certificate and am ready to work! I’m hearing different things about the work permit:

a: Labour office tells me that I cant work as a freelancer and that a company has to apply for a work permit for me

b: Labour office tells me that I dont need a work permit

c: friend tells me that I have to do nothing

I dont know what to do now. It is very annoying cause I want to work and not illegally.
Can somebody tell me?
