1. Major banks in Hong Kong have strict requirements on the information of credit card applicants, and credit cards of different grades are approved only by evaluating the assets and income of the applicants.

For example, in Hong Kong, it is generally said that a gold card needs an annual salary of 6, Hong Kong dollars, a platinum card needs 15, dollars, and a platinum card needs 25, dollars in some large banks. However, only a few customers who have been invited by banks can apply for the most distinguished black card.

2. To apply for a credit card, you generally need to provide the bank with the bank statement and payroll for the last three months, and the ID card of a Hong Kong resident. If you are not a permanent resident, you need to provide an additional work visa, a company certification letter and a work contract if necessary.

3. In addition to the above approval conditions, the bank mainly depends on how much assets you have and whether your credit history is good or not. For example, if the bank where you apply for a credit card happens to be the bank where your current account, fixed account, insurance account, stock account and fund account are located, the chances of applying for it are much higher.
