It should be noted that you need to have the corresponding financial resources to apply for the quota. If your income is high and your working conditions are excellent, your success rate of applying for a high amount will increase.
In addition, if you have a bad credit record before, it will be difficult for you to increase your credit limit. Bad credit records have a great influence on whether you apply for a credit card, increase the credit limit, or apply for a car loan or mortgage. If you have a bad record before, you need to apply to increase the credit limit of the credit card, and the bank will definitely not pass. When the bank examines the materials you submitted, it sees that you have a bad credit record and will definitely not handle it for you.
