At present, the maximum amount of ICBC credit card online application is 2000, usually 500. If you just applied for a quasi-loan, it is estimated that you can apply for another credit card, but the amount is definitely not 5000, basically 500.
If you really like ICBC, you can apply, then use it every month, and then apply for an increase. If it is estimated to be normal, it will soon be mentioned as 5000.
