INS v. Aguirre-Aguirre, a 1999 decision, the Supreme Court chastised the Ninth Circuit for questioning the executive branch’s judgment in deporting Colombian students who were accused of violent political crimes.  Immigration decisions are political and national security decisions that President Trump has wide and broad discretion over.  President Obama issued a last minute executive order ordering Cuban's to be returned to the Cuban regime even though he knew they would be subjected to imprisonment and death.  Not a peep from the left.
