Thanks a lot. I researched that a while ago before getting divorced, and back then was convinced that a marriage based APRC gets cancelled after divorce. Looking around on Forumosa now (since the Taiwan immigration website is currently down…) it looks like you are indeed correct. I’ll check directly with the NIA when I go to apply. I believe I’m already eligible for an marriage based APRC now, so if this is not an disadvantage it would be perfect 
So far I saw that yes they can come, but not permanently - just for a year or so. See The Employment Gold Card Super-Thread - #237 by Brianjones
