According to my love card website, the time required for the credit card review of China Merchants Bank depends on the application materials and the bank's review process. Generally speaking, the review time is about 10 working days. During this period, the applicant needs to receive a credit call from the bank, which does not mean that it is approved, but that the bank wants to know more about the applicant. After receiving the call, the bank will give the corresponding audit results in about 3 working days.
