If you work locally, your card will be mailed to other places. The bank must think that you are either not from this company or are going to resign.

This is not a question of mailing, but a question of approving cards. Many banks can't hand in your application form. How can there be the following?

Credit cards are regional. You can apply for a credit card at your place of work. If you are on a business trip, you cannot apply for a local credit card.

There is only one kind of people who apply for cross-regional credit cards, business people who travel all over the country and provide financial proof to apply for cross-regional credit cards. And the card approval rate is not very high.

Because credit cards are the same all over the country, banks only recognize local ones.
