1. Since wages are paid through ICBC, as long as there is no problem with your credit record, your application for a credit card will definitely be approved. If you consider the practicality and benefits of credit cards, I personally think that China Merchants Bank cards are better. There will be certain discounts at many merchants, especially in catering and entertainment venues. You can choose by yourself.
2. Information provided: original and copy of ID card; account details of salary card issued on behalf of the employer; work certificate or real estate certificate issued by the unit (because you have a foreign registered permanent residence, you must have it to prove that you Reside in the local area for a long time). This is the most basic information provided, which is enough to apply for a card, but if you can also provide other financial proof, it will be helpful to increase the limit. For example: deposit certificate, real estate certificate, driving license or car purchase certificate, account details of our bank's or other bank's gold card, etc.
3. The time is not very certain. In theory, ICBC can get it in 5 days at the fastest, but it may be slower than 10 days due to human reasons. If it's China Merchants Bank, it won't take long, because China Merchants Bank happens to have a card issuance center in Shanghai.
