Everbright Bank does not explicitly limit the time for reapplication after credit card cancellation, but suggests reapplication after 6 months.

If the time between card withdrawal and card processing is too short, the bank may think that you have returned the card maliciously, thus affecting the approval and quota of the new card. For example, many people will cancel their credit cards because the credit card limit is not high, so applying for a credit card from the same bank will affect the pass rate.

If you are worried that you can't pass the exam, or you can't wait for half a year before applying, you can try to apply for a credit card from another bank.
