See here for USCIS announcement.
There are still SIGNIFICANT consequences for sending your family members to the consulate abroad after winning a waiver. I have seen many incompetent attorneys and notaries send people to Ciudad Juarez and other consulates who were permanent bars or who had other issues that end up being denied and have no way back into the country. PLEASE seek competent legal help to analyze these new and ever-changing immigration laws.
