If the credit card application is rejected, it may be because the poster did not submit materials other than proof of employment when applying, because the credit card application requires the review of the applicant's personal qualifications. If the personal qualifications are not good, The chance of a successful application is relatively low. In addition, if the bank discovers that the applicant's information is falsified during the credit reporting process, the application will not be successful. In addition, if there are bad records in the poster’s credit record, it will also lead to the rejection of the credit card application. Therefore, there are many reasons for the rejection of the credit card application. The above is the information I know. I hope my answer can help the poster!
