You can also apply on your own initiative. In order to retain customers, some banks will generally accept your withdrawal application. Usually, after the cardholder normally uses the credit card for half a year, he/she can take the initiative to submit a written application or adjust the credit card limit through telephone service, and the bank will increase the limit after approval.
