That will be the challenge...they need to stop more coming in, then maximize self-deportations (eVerify probably the quickest move). Figuring how to deport any that come into contact with law enforcement will help but probably slow. Probably need 10s of thousands of judges, reschedule hearings, then deport. Plus, round up everyone that has missed their hearings. Lastly, Biden has given work permits to most once they have been in the US for a bit, need to rescind those. It is going to take a concerted effort across the board, everywhere, and no time limit, not ‘couple of million’ and done. There are 30-60 million to remove from the US. Succeeding in that will be one of Trump’s greatest successes. And it won’t be easy.
Stop all freebies except for bus rides and a lunch to go. They will self deport.
