What you want to ask is that the bank card has been frozen. What should I do if I illegally operate foreign exchange? The freezing of bank accounts by public security organs is an investigation measure, which should be related to the case. The treatment method is as follows:

1, go to the public security organ to explain the situation.

2. Public security organs investigate bank accounts and cases.

3. When the investigation does not involve illegal foreign exchange operations, the public security organ will issue a unfreezing notice to inform the bank to unfreeze the bank card.
