Can those currently in and legally employed in Taiwan with an ARC and a work permit enrol into a degree course at a university?
Hypothetical situation: You have an enjoyable legal job in Taiwan of few hours that you want to keep doing that leaves you plenty of time to do university study, and are fully able to self-support yourself financially (healthy savings, pension, sugar daddy/mummy, whatever). You decide you would like to undertake a master’s degree course at a university in Taiwan while continuing to work. Presumably anybody with an ARC can walk into a university that takes international students, apply and enrol. There should be no problem doing this as long as you can fulfil your study obligations and your employment obligations.
