2. Let the bank feel that you are suspected of maliciously handling the card, and it is more likely to be rejected in the future;

3. Even if a credit card is issued, the amount may be low, and it is difficult to apply for a credit card with a higher amount.

It is recommended that you do not apply for more than one credit card at a time to ensure that you can apply for one card.
