Can China people be presidents of other countries?

I know America better. In the United States, there seems to be a requirement for immigration. It seems that more than three generations of foreigners can run for president of the United States. Otherwise, they can only be senior government officials at most. Like Schwarzenegger, he seems to be Austrian himself. Therefore, he can be a governor at most after taking office and has no right to run for president. I don't know whether immigrants can be presidents in the civil law system, but I guess I dare not let immigrants run for national leaders in any country. After all, there is a crisis of infiltration, and the requirement for immigrants for more than three generations is also for immigrants to truly recognize their own culture, become real citizens and safeguard their own interests.

I hope my analysis can help you.
