Thousands of young undocumented immigrants line up to apply for deportation deferment, but concerns remain

As thousands of young undocumented immigrants across the country begin lining up for the forms that will allow them to take advantage of President Obama's executive order sparing them from deportation for at least two years, questions are already being raised about the long-term effectiveness and permanence of the program.

Should these young people be concerned about officially revealing themselves as illegal immigrants? Will the President's order face future challenges from Congress? And what happens if Mitt Romney wins in November? Joining us tonight to discuss are journalist and undocumented immigrant Jose Antonio Vargas, famous for penning a 2011 New York Times Magazine piece revealing his illegal status, and David Leopold, the former president of the American Immigration Lawyers Association.
