From what I have heard through our lobbyist, they will replace that with a new bill or put in the new "Z" visa option. Z Visa as thought out by our great president. What it is that it would allow undocumented people to have legal status for 8 years. After 8 years, head of the household would have to travel back to his/her native country & get stamped at a consulate for visas for all his family members in the country already. Then they would apply for their GCs once the head of household returns back. So theoretically 15 years from now(2022) to get their citizenship.In the 15-17 years, they would have to remain employed, paying taxes and commit no crimes.
The sticking point is about family members stuck back home for all the undocumented. If they give them visas to immigrate, what about legal immigrants(GCs) spouse & kids? Thats where things get complicated. Congress won't separate their families for 22 years so they are trying to come up with something that pleases everyone...Making F2a category as immediate realtives(just like USC) and eliminating the brother/sister of US citizen visas.
