For the bank and other financial institution statements required for the affidavit of support (for those using assets to show support), how "official" should the statements be? Do they need to be signed letters from the institution, or can you use the regular monthly statements that you get in the mail? I've been requesting my banks to send me official signed letters verifying my assets, but 2 of them keep messing up the request and it is taking forever to process this....
Thanks!
