Although your company can't stamp you, you can apply for a credit card without providing proof of salary.
You can provide a copy of your work permit or work permit, and attach your photo, business card, etc. Go to China Merchants Bank, CITIC Industrial Minsheng, etc. Don't go to state-owned banks to approve credit cards with high conditions and low quotas.
In addition, you don't need to provide your real estate license, because it is not in your name and is invalid.
