After marrying a woman in Taiwan Province Province, can the man become a citizen of Taiwan Province?

Yes, if you get married, you can get an entry permit to Taiwan Province Province, and then you can go to Taiwan Province Province, but the examination is very strict (mainly to prevent some fake marriages).

If you are asking about Taiwan Province citizenship, you must meet some requirements.

1. Married to a native of Taiwan Province Province and lived in Taiwan Province Province for more than 8 years.

2. Stay in Taiwan Province Province for at least 183 days every year.

3. Accompany the spouse of Taiwan Province Province to apply for settlement at the Immigration Bureau.

4. To apply for settlement, you must provide proof of renouncing mainland citizenship.

Anyway, it's quite complicated, and it usually takes about half a year to handle it.
