Hi thourb, just wanted to let you know that I did exactly that - submitted my 6 month credit card statement and wrote a LOE. Now I have the COPR and looking to move this August/September! Hope your move went well!Submitted the latest statement for each of my credit cards, nothing more. Stated in a letter of explanation words to the effect of "As requested, I enclose my latest Credit Card statements showing my outstanding debts. No money was borrowed from these credit cards to facilitate immigration and I have no further undisclosed debts".
Good luck with your application, at least you know now that this isn't an issue!
