I would strongly advise you to search previous threads on this topic. There are some that are very informative.
In the past, you’d want to apply for an Open Work Permit–which would make you a free agent. Not sure with all the changes lately if this (previously critical) step is still necessary. But do check!
You will also want to let your banks and other key financial players in your life know about your new status.
Next, you should apply for open work permit so you can tell your employer you’re now on APRC. They need to know so that they won’t need to re-apply your work permit when it expires coupled with the ARC.
just so you guys know, I’m here through marriage so some of the info may not apply to me. For example, I’ve always been able to change jobs as I wanted on the ARC.
One thing I’ve never understood: if you have a JFRV, you don’t need an open work permit, right? You’re good to go? But then if you were to change to the APRC, you have to apply for the open work permit. It sounds like a bit of a downside to the APRC in a way, and I don’t understand why the same rules wouldn’t apply to both.
That being said, the open work permit was one of the best experiences I’ve had applying for something in Taiwan. The guy was really nice and it took no time at all.
For me it stayed the same. My company still handles the NHI after changing over. Should I leave that company, the new one would pick it up or if I go out on my own I need to pay my own premiums. For the latter, I don’t know the details, but that’s how it was explained to me.
You can now apply for an open work permit, which means you can do pretty much anything you want including starting your own business flipping burgers on a street corner. You might be able to argue your way into free admission to museums/parks/zoos which are free for citizens only because of your permanent residency which very nearly is citizenship but this would be pretty hit and miss. I think you can vote in local council elections (but not national elections)? Someone correct me on this if I’m wrong, I might be getting confused with Japan.
