If you have a very long history with a bank, however, that might factor into that bank's decision in giving you a credit card. Nothing stops banks from combining credit score data with other sources.

As a personal anecdote, I avoided credit cards until age 31, but had a bank account with Wells Fargo since I was 16. Because I had no history, almost no one wanted to give me a card despite my high provable income. I got my first credit card with capital one (for a hilarious 300 dollar limit).

But two months later after I became a known credit card user I started getting credit card offers in the mail from a variety of sources -- Wells Fargo offered me considerably more credit than the others, presumably because some system of theirs thought I was more trustworthy (long-standing account history? Actual visible income in the bank account?) They even offered me a rewards card even though I only had 1 month of history.

I am well aware of that and I never claimed it did. I wasn't talking about credit history but about history as in, a customer in a bank for years. These are also factors for how easy/hard things like this is.

Having a history with a bank has no impact whatsoever on your credit report.

This has nothing to do with your credit report or your credit history.

This has to do with your chance of getting a credit card to begin with. There is a difference between being a US citizen having had bank account most of your life and then being a foreigner who just got yours.

Not sure why you keep insisting I am saying something else than I am.

Because you're not being at all clear and you're still incorrect.
