Can China people go to the United States after they get a white card?

Of course. During the validity period of the visa, China citizens can enter and leave the United States multiple times with a valid white card visa. The white card visa has expired or been cancelled, or the holder has violated the law or regulations, which will affect his eligibility to re-enter the United States. Students have the right to decide whether to allow admission according to their personal circumstances. Therefore, if a citizen of China holds a US white card visa, he should abide by the relevant regulations within the validity period of the visa to avoid violating laws and regulations, so as to ensure his re-entry into the United States.
