If you don’t already know, once you become a taiwanese citizen you have free run of china for any purpose, just like British citizens in the EU before Brexit. It’s basically one country two system in all but name.
I do not know if you can get them family visas in china as a Taiwan compatriot however.
I think however most taiwanese don’t seem to care whether Taiwan is under kmt, dpp, or ccp.
Why do you think there’ll be any benefits? Where are these benefits coming from? An overlord that couldn’t care less? Crippling US sanctions? Forced strategic technology transfer to mainland? HK didn’t benefit, Taiwan won’t either.
I’m not saying there are benefits, but it doesn’t have to be a global disaster if there is a peaceful reunification, given the OP said “have you ever considered the benefits of a mainland Chinese controlled Taiwan?”
Do you think China would recognize your citizenship? Seems to me foreigners given citizenship by a government the PRC doesn’t recognize as legitimate would not just be considered Chinese…
The rule of law only exists in democracies. Do you really think they’re going to respect the rules of the ROC?
Several points:
China strictly enforces single citizenship. As someone intending to restore their UK citizenship, you might be investigated and asked to choose one. You really going to give that up?
You’re white. China is quite Han supremacist, whether or not you still have your UK citizenship might be irrelevant. You might be deemed as attaining Chinese citizenship under false pretenses and have it stripped. There is a reason why authoritarian countries have tonnes of stateless people compared to democracies. If you have your UK, you might be expelled. If you don’t have it, well, you may be stateless and living in limbo while they wait for you to figure out how to leave, or they might just put you in a camp.
China allows Hong Kong and Macau people to have second citizenships, no reason to think they wouldn’t do the same with Taiwan unless it was totally integrated with no special status, which is unlikely.
If it came to it I’d choose my British passport over my Taiwan one during a war, but only if I was able to stay in Taiwan with my British passport, which would probably not be possible.
However at this point I’m not sure that I will be getting my UK citizenship back. It’s not 100% guaranteed the UK government will allow me to resume. They have no reason to deny me but you never know. Right now I’d rather have the Taiwan passport and have me, my wife and child all holding a common passport so we are less likely to be separated.
