A bipartisan group of senators has largely agreed on a broad immigration bill that would require tough border measures to be in place before illegal immigrants could take the first steps to become American citizens, reports the New York Times. The bill does not impose any specific measurements of border enforcement results that, if they were not met, would stop the immigrants from proceeding toward citizenship. It allows a period of 10 years for the Department of Homeland Security to make plans and use resources to fortify enforcement at the borders and elsewhere before it sets several broader hurdles that could derail the immigrants' progress toward citizenship if they are not achieved. During the first decade after passage, the bill sets ambitious goals for border authorities – including continuous surveillance of 100 percent of the U.S. border and 90 percent effectiveness of enforcement in several high-risk sectors – and for other workplace and visa enforcement measures. It would authorize $3 billion for Homeland Security officials to meet those goals during the first five years, with a possibility of additional financing.
