Where can I apply for a long-term residence permit in Taiwan Province Province?

At present, apart from getting married, you can't "stay long" in Taiwan Province Province unless you go there as an exchange student or invest in mainland enterprises in Taiwan Province.

Need to apply for "Mainland residents traveling to and from Taiwan Province Province". It's called "Taiwan Entry Permit". If you are a citizen of People's Republic of China (PRC) and have no immediate family members within three generations in Taiwan Province Province, you cannot live in Taiwan Province Province at present. You can't get into Taiwan Province Province except traveling with a group.
