Yes, the quota is not full yet. The dollar limit of CCB credit card is mainly determined by the issuing bank according to its personal information, including personal monthly income, personal credit score, personal occupation and other factors. Banks will also consider factors such as the frequency of credit card use and repayment records. Low personal credit score or strict bank risk control policy will lead to insufficient US dollar limit of credit cards, so the US dollar limit of CCB credit cards is not full. Improving the credit line needs to be combined with the rational use of credit cards and maintaining good repayment records, and it is forbidden to abuse the credit line.
