WASHINGTON — Far-reaching legislation to grant a chance at citizenship to millions of immigrants living illegally in the United States cleared the Senate Judiciary Committee on a solid bipartisan vote Tuesday night after supporters somberly sidestepped a controversy over the rights of gay spouses.
The 13-5 vote cleared the way for an epic showdown on the Senate floor on the measure, which is one of President Obama’s top domestic priorities yet also gives the Republican Party a chance to recast itself as more appealing to minorities.
The committee’s action sparked rejoicing from immigration activists who crowded into a Senate committee room to witness the proceedings. ‘‘Yes, we can!’’ they shouted.
In addition to creating a pathway to citizenship for 11.5 million immigrants, the legislation creates a new program for low-skilled foreign labor and would permit highly skilled workers into the country at far higher levels than is currently the case.
At the same time, it requires the government to take costly new steps to guard against future illegal immigration.
There was suspense to the end of the committee’s deliberations, when Senator Patrick Leahy, the Vermont Democrat who serves as chairman, sparked a debate over his proposal to give same-sex and heterosexual spouses equal rights under immigration law.
‘‘I don’t want to be the senator who asks people to choose between the love of their life and the love of their country,’’ he said, adding he wanted to hear from others on the committee.
In response, he heard a chorus of pleas from the bill’s supporters, seconding private appeals from the White House, not to force a vote that they warned would lead to the bill’s demise.
‘‘I believe in my heart of hearts that what you’re doing is the right and just thing,’’ said one of them, Senator Richard Durbin, Democrat of Illinois. ‘‘But I believe this is the wrong moment, that this is the wrong bill.’’
In the hours leading to a final vote, the panel also agreed to a last-minute compromise covering an increase in the visa program for high-tech workers, a deal that brought Senator Orrin Hatch, Republican of Utah, over to the ranks of supporters.
Under the compromise, the number of highly skilled workers admitted to the country would rise from 65,000 annually to 110,000, with the possibility of a further rise to 180,000, depending in part on unemployment levels.
Firms where foreign labor accounts for at least 15 percent of the skilled workforce would be subjected to tighter conditions than companies less dependent on H-IB visa holders.
The compromise was negotiated by Hatch, whose state is home to a growing high tech industry, and Senator Chuck Schumer, Democrat of New York. It is designed to balance the interests of industry, which relies increasingly on skilled foreign labor, and organized labor, which represents American workers.
AFL-CIO president Rich Trumka attacked the deal sharply as ‘‘antiworker,’’ although he also made clear that organized labor would continue to support the overall legislation.
Robert Hoffman, senior vice president for government affairs at the Information Technology Industry Council, welcomed the deal.
The issue of same-sex spouses hovered in the background from the start, and as the committee neared the end of its work, officials said Leahy had been informed that both the White House and Senate Democrats hoped he would not risk the destruction of months of painstaking work by putting the issue to a vote.
