What should I do with my passport if I travel to America and then get black in America?

America won't do anything about passports.

Because you are still a citizen of China, holding a China passport, but you have a bad record in the US Immigration Service. If the US Immigration Service finds out, it will not be able to go to the United States in the future, nor will it get a visa.

Moreover, it is even more impossible to become a regular American hukou in the future. Once you have a bad record in the US Immigration Service, your application for a regular US account will be rejected.
