They will be allowed to stay and work here, the object of their crime. Green card holders are on probationary status. So will they have to get health insurance or be able to use the ERs as free medical clinics? What are the terms of their probationary status? Will all 12 to 20 million have to register their names and be issued ID cards? Will they receive work permits? Will their future children born in the US still be citizens? Will they be entitled to SS and Medicare since they are contributing to the system? What is the cut off date for their probationary status?
And it might be just a way for the elites to introduce classes of citizenship. They envy the old Hindu caste system.
