First of all, point out: Green card: A green card is a permanent residence permit for foreign citizens. Holding a green card means that the cardholder has permanent residency in the issuing country, and at the same time, holding a green card can exempt the entry visa for a certain period of time.

so the green card has nothing to do with anything else.

Gold card, silver card and dragon card are all credit cards.

Credit card, as its name implies, is a bank card that can give you a certain overdraft limit according to your credit, and you can spend first and then repay.

Among them, the amount of a gold card is larger than that of a silver card, and fixed assets should be used as collateral when handling a gold card. For example, my friend used a car as collateral to handle a gold card with an overdraft limit of 5,. As for the silver card, it is a little lower than the gold card. I haven't done it, and I don't know what I need to mortgage. Gold and silver cards can be handled by all banks, because all banks have credit cards, and if there are credit cards, there will be gold and silver cards.

Longka is special. Longka ordinary credit card is a credit card issued by CCB to customers with ordinary credit limit in CCB.

In a word, Longka is a unique credit card of China Construction Bank.

That's basically it. Don't confuse the green card with the credit card in the future.
