President Barack Obama is expected to lay out his principles for immigration reform in a speech in Las Vegas today that will include a potentially quicker path to citizenship than the bipartisan plan a group of senators unveiled earlier this week.
The president will offer some new details about the White House’s immigration reform plan, which expands on a blueprint  it released in 2011, a senior administration official told ABC News. But for now Obama will stop short of offering his own piece of legislation because of the progress made by the Senate “Gang of Eight.” 
The White House has sounded positive notes about the Senate group’s plan thus far, but the specifics that Obama announces are expected to have some key differences that might cause concern for some Republican senators who have signed onto the senate deal.
Like the senators’ plan, Obama’s proposal calls for a pathway to citizenship for many of the 11 million undocumented immigrants living in the U.S. The senators’ plan would grant “probationary legal status” immediately to eligible undocumented immigrants, but would not allow them to apply for permanent legal status, or a green card, until the border is deemed to be secure. Think of that as a trigger system.
