No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
I would advise careful review of the current VA loan underwriting requirments, particularly as to lates/derogs within the last 24 months.
Additionally, while I believe that VA does not, per se, set a min mid FICO score, I believe that your individual lendor can and usually does, with a mid-score of 620 usually being required.
I would have a chat with your prospective VA lendor as to "what now"
