I am going into my lawyer's office today to review my Chapter 7 paperwork, and he is going to file tomorrow. I'm very relieved that my financial stress is on the road to resolve. I do have a couple of questions:
If you do go for another credit card right away, go for a secured card, not an unsecured one - Capital One and Discover are the most frequent sources recommended, and lately people are recommending Discover over Cap 1. However, check another recent thread which reports that applying for a secured Discover too soon after being discharged from BK might result in a denial. I think I would actually give it a few months after discharge before applying for a secured card; when I was discharged from my Chapter 7 in December 2014, I waited a year before applying for my secured Cap 1 the following December, and was approved without issue at that time. You don't have to wait nearly so long but do check your FICO scores first and make sure you can load a decent amount into your deposit.
I didn't attempt to keep any credit cards in my own BK because I was carrying high balances on all three of them, so I can't provide any specific advice there.
