Should I change my nationality when I settle down?

No, for example, if you want to settle in Singapore, you can get permanent residency without changing your nationality, which will make it much more convenient for you to travel between Singapore and China, and save a lot of unnecessary things, such as visas and passports, which are allowed by law. So the United States is also like this, and the United States also supports dual citizenship. Both methods are feasible. If China people are in the American entertainment circle, to put it bluntly, they mix well, have two skills, and the probability of being appointed is not low. As long as you believe that you have the ability, there is hope! Good luck! my friend
