This is very simple. As long as you have the income certificate issued by the financial department of the unit and affix the official seal, you can decide the overdraft limit and consumption limit of your credit card according to the amount of the income certificate. Several big banks I know in Dongying are basically barrier-free, so you can take any documents then. Now banks are eager for you to apply for a credit card, because now banks have related transactions with many businesses, and every credit card consumption has a commission ratio. Being away from home is not a problem, not to mention that you are from Weifang. Once your identity information is verified, it can be found in all bank databases in the country that you can't run away (hehe, don't worry, just talk about it), and the minimum overdraft limit is 900+ 3000.
