Durbin's legislation provides a pathway to citizenship for the young immigrants provided they show good moral character and are working toward completing a degree at a college or university or serving in the military. By contrast, Rubio's proposal (which he plans to introduce in the form of legislation later this summer) provides non-immigrant visas to young illegal immigrants but does not provide a pathway to citizenship.

Rep. David Rivera (R-Fla.) also introduced a House bill that would grant non-immigrant status to young illegal immigrants provided they came to the United States before they were 16 and lived in the country for five continuous years. Rivera's legislation provides a pathway to citizenship.

Durbin and Rubio have both expressed a preference for their respective plans over the other proposals.

Despite the multiple proposals, House Speaker John BoehnerJohn Andrew BoehnerGOP sees omens of a Dem wave in Wisconsin Dems face hard choice for State of the Union response Even some conservatives seem open to return to earmarks MORE (R-Ohio) has said he does not expect any of them to become law this year. Additionally, the House has refused to take up Durbin's DREAM Act, the senator noted.

"I first made this request of the administration two years ago and renewed it with the support of 21 Senators last year," Durbin continued. "Because the House has refused to consider the DREAM Act and a filibuster blocked it in the Senate, this presidential action was absolutely necessary to serve the cause of justice."
