The US president has said the time has come for a review on the US immigration system. He made his 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 devise a path to citizenship for many of an estimated 11 million undocumented immigrants in the US. He noted that the current system was "out of date and badly broken". The president’s case for an immigration reform reflects a plan he rolled out three years ago, though that did not go far. The president now backs the Senate plan including making illegal immigrants pay taxes and fines, and sending them to the back of the queue before they can become American citizens. After eight years, individuals would be allowed to become legal permanent residents and would eventually become citizens five years later, according to his scheme three years ago.
