ARC's, Work Permits and Visas - what do you need to know?

Thanks for that @yyy.
I would like to add that there seem to be slightly more obscure ways (or maybe just one way) to gain legal employment in Taiwan that does not require as large of a time commitment.
@Toe_Save has a company that helps artists work legally in Taiwan:

He also indicated that it would be possible through his company to gain an ARC and work permit with just occasional work:

Work on the occasional commercial set as a background model in Taiwan and study full-time at a university in Taiwan? Looks doable. Biggest factor is whether or not that would be okay with Toe_Save.
