I currently hold a ts/sci, to preface I was sitting at about a 750 credit score and like a year ago I went through the process of getting a new credit through my bank. I don’t even know how it happened but ig 2 cards were made under the same account, all charges were going to both. I wasn’t aware and the charges built up and became late and essentially cooked my credit. Now I’m sitting in the low to mid 500s. Im alr taking the steps of getting it fixed but I wonder, is something like that enough to revoke my clearance.
