As far as I know, the temporary quota of ABC cannot be directly converted into a fixed quota, and every bank does not have this policy. If you want to have a high credit card for a long time, you can apply for permanent withdrawal, but you need to meet the following conditions before applying:

1. It takes six months to apply for a credit card for permanent withdrawal.

2. The monthly credit card limit is close to or exceeds the credit card limit.

3. During the use period, the overdraft limit is mostly one-time repayment.

4. No bad records such as overdue.

If the above four conditions are met, you can apply to the bank for quota adjustment. The general quota is adjusted to increase by 50% and be halved on the existing basis. I hope my answer can help the landlord!
