In a June 15th memo announcing deferred action for immigrant youth, DHS Secretary Janet Napolitano gave USCIS 60 days to come up with a process that will allow these young people to affirmatively apply for the chance to work, study, and live in the U.S. without fear of deportation. To be sure, USCIS staff and their counterparts at ICE, CBP, and DHS, have been entrusted with a difficult job—one that requires balancing legal and practical implementation issues against high expectations and years of built up frustration over the lack of immigration reform. But the real challenge is acknowledging that every single decision they make about the program has the chance to make it harder or easier for young people to realize their dreams.
