Good Luck. They're pretty awesome. I'm roughly 3 years post ch 7 and have a total of 16,000 in credit lines with NFCU. 2 cards, platinum and the Cash Rewards. Pay it on time and every 4-6 months request a credit line increase through the website. I don't think they even soft you for it, It's ALWAYS, ALWAYS, ALWAYS given me limit increases. Never once has it referred in for a review or declined me. They rock. Try to get in with USAA too if you can, they're great as well! NFCU and USAA are my two favorite post bk-7 friendly credit card issuers/banks.
idk about everyone else, but Army Reserve was my ticket in. Ask around in your family - I'm sure there's a way you can get in as well!
My dad was honorably discharged from the navy. I highly doubt he would give me the last four of his SSN to get an account. My sister works for dfas but is not a member of nfcu.
