bump...been getting offers in the mail for capital one credit card. Just applied for the heck of it and to my surprise got approved. Definitely ecstatic right now but got a few concerns if any of you credit card gurus can help. How exactly will I be able to build credit using the ITIN? If I was to get a SSN in the future...is there a way to have it replace the ITIN by the credit agencies? I just want to ensure I build credit from now on and it doesn't go to waste.
