can you change x2 visa to x1?

If the school can provide proof to prove that you need to study for a long time in PRC, I think it is possible for you to change X2 type to X1 type at the exit and entry administration of the local PSB. But if it cannot be done, I’m afraid you need to go back to your country to apply for a student X1 type.

If you want to change school, you need to get the dropout certificate from your previous school and the admission letter, and JW form from the new school. And then you take the required documents to the local PSB where the new school is located to renew your residence permit.
