You can apply for 2 to 3 ICBC credit cards of each type, but you cannot apply for more than 2 at one time. After applying for the first credit card, the cardholder generally needs to use the card for 3 months before applying for the next card. However, applying for a new card may share the same limit as the old card. Assuming that the old card has a limit of 10,000, the new card will not increase the limit. The total limit of the two cards combined is 10,000, unless the limit is 10,000. The limit will be increased only if the cardholder can provide more proof of financial resources.
