In 2012, Congress reached a deadlock on a program that would have protected young immigrants from deportation if they had been brought to the U.S. as minors.
It's only January, but the U.S. Supreme Court has already tabled any hearings on the legality of the Deferred Action for Childhood Arrivals (DACA) program until at least this fall. Assuming the court sticks to its usual practices, that likely means no decision would become available until 2020.
The Deferred Action for Childhood Arrivals program (DACA) provides protection from deportation and grants work authorization to qualifying non-immigrants who were brought to the U.S. before age 16. Currently, the U.S. Citizenship and Immigration Services is no longer accepting new applications, although it is processing renewals. However, an April court decision, currently on hold, could potentially open the program up to new applicants.
