U. S. President Barack Obama has said the time has come for a review on the U. S. immigration system. He made this case at a high school in Las Vegas, Nevada, a day after a group of senators outlined a framework for reform. The White House and senators conceive a path to citizenship for many of an estimated 11 million undocumented immigrants in the U. S. He noted that the current system was "out of date and badly broken". Mr. Obama’s case for an immigration reform reflects a blueprint he rolled out in 2011, though that did not go far. Mr. Obama now backs the Senate plan including making illegal immigrants pay taxes and fines, and sending them to permanent residency and eventual citizenship. After eight years, individuals would be allowed to become legal permanent residents and would eventually become citizens five year later, according to his 2011 blueprint.
