As thousands rallied on Capitol Hill, more details emerged on the Senate’s bipartisan immigration talks. The proposal sets what some call impossible goals on so-called “border security” before undocumented immigrants can obtain green cards. According to The Wall Street Journal, U.S. immigration officials would have to certify complete monitoring of the southern U.S. border and a 90 percent success rate in blocking unlawful entry in certain areas. Only then could the nation’s estimated 11 million undocumented immigrants apply for permanent residency. The process is expected to take at least 10 years. The current proposal also maintains a timetable of at least 13 years for undocumented immigrants to become eligible for citizenship.
