1. Your registered permanent residence has always been in the police station where the school is located, which means that your registered permanent residence has always been in the collective household of the school, and there is no problem with the migration certificate. The paper given to you by the school may be a household registration certificate or a receipt.

2. Under normal circumstances, after students move their registered permanent residence into the school, the school will centrally handle the replacement of health cards. I suggest you consult the class teacher clearly.

The bank says your ID card doesn't exist. There may be something wrong with the banking system, or the citizen ID card information system has not been updated in time, or your ID card has expired. I suggest you take your ID card to the local police station for verification.

4. After graduation, whether you find a job or not, if there is no unit to accept your account and file, your account and file must be returned to your original place. If you don't go back to your hometown to settle down, then your account may be gone, and it's not easy to get it back later.

Every step, I hope you can consult a senior person. Otherwise, it is difficult to solve the problem.

Good luck!
