Hi, I have a question on the check sent to USCIS for filing fees. It's my wife's case, however, our check was printed before we got married so that there is only my name on the check, plus she never signed a check before, we do not even know if it works for her. So if we use our check (only my name is on it) and I sign the check, will it be a problem for USCIS? Thanks.
