I was just mentioning that getting GC through your mother was slow. But if you are out of status now, or won't be able to maintain status until the visa number is available on your mother's petition, then yes, that will be a problem, because for non-Immediate-Relative categories, you need to be in status to file for Adjustment of Status.
Filing as the spouse of a U.S. citizen, you are in the Immediate Relative category and don't need to be in status to file for Adjustment of Status. Nothing is "waived"; you have no ban yet and whether you are in status is not relevant for eligibility. You don't need a lawyer unless you want to.
