I'm American, and have no reason to believe the credit reporting services are aware of my physical location. This is evidenced by conversations I have had with various agencies (governmental, credit bureaus, etc.) over the past year.
> For comparison, I had a very easy time getting 3 unsecured cards back when I was a student with nearly zero income. It also helped that I had checking/savings accounts with the same banks and years of deposit history.
I've used the same primary bank for 20 years and counting.
