Income issues for APRC applicants

isn’t it a naturalization? I’ve heard that the spouses of TW’ese who are from East Asian nations often choose becoming roc citizens instead of getting aprc.

is this mean you left taiwan after that? If you have been here continuously, I think you are still eligible. If so, you cannot apply again, once it was rejected?

Aren’t the income criteria different between the spouse of TWnese and other foreigners?
