Business and labor groups have reached an agreement to establish a new low-skilled worker program, clearing one of the last major hurdles to legislative efforts to overhaul the nation’s immigration laws.

The U.S. Chamber of Commerce and AFL-CIO resolved differences on how many visas should be offered in a program for temporary workers and how much those workers should be paid, according to a report from the Associated Press.

The agreement on a critical issue business groups and organized labor have battled over for years will likely bolster efforts in the Senate to finalize a comprehensive immigration reform package a bipartisan group hopes to unveil in April.
