WASHINGTON, D.C. -- Earlier this week, a group of bipartisan senators announced a blueprint for immigration reform. On Thursday, Senator Charles Schumer says he is hopeful that the blueprint will turn into reality. But he says that all depends on whether Republicans and Democrats can overcome some critical obstacles, including how to define border security, a path to citizenship for the 11 million undocumented immigrants and reaching an agreement with business and labor how to devise a guest worker program.

The path to citizenship has been getting a lot of attention, mainly because key Republican Senators have agreed to do it, provided the borders are secure enough.
Under the blueprint, a panel of border state governors would help decide whether the borders are secure, but Schumer says the final decision would lie with the Department of Homeland Security.

“What we've proposed is that the DHS security will have final say on whatever metrics we propose are met. We think those metrics will be quite objective. They will be objective, so there is not much leeway. But what we envision is that because they be objective, in all likelihood the committee and DSH will agree,” Schumer said.

The biggest hurdle, perhaps, in getting immigration reform passed will be the Republican controlled House. Schumer says he is working with House members, who are also devising a bill, and he believes that if a large number of Republican senators support immigration reform, it will have a much better chance of passing the House.
