As far as I know, once the credit card application is submitted to the bank, it cannot be modified. If the landlord finds that his information is wrong, he can directly contact the customer service hotline of the issuing bank for consultation. If the staff says it can't be modified, then the landlord's credit card application should not be successful this time. I suggest that the landlord wait three months before applying for a second credit card. Before submitting, he must ensure the accuracy of the information. That's all I know. I hope my answer will help.
