It depends on your recent credit card use, including the number of consumption, the amount of consumption, whether the repayment is timely and so on. Generally speaking, the Bank of Communications credit card can apply for cash withdrawal once every three months at the earliest. Under normal circumstances, it has been used for half a year or one year, and it has no bad credit record and is in good condition. The Bank of Communications will automatically withdraw the amount. Of course, whether it is automatic withdrawal or you take the initiative to call the bank's customer service phone to apply for withdrawal, Bank of Communications should review your daily card use. If your credit limit is never used up, the bank may think that you don't need a higher credit limit, or it may not take the initiative to cancel it.
