Vermont Sen. Patrick’s Leahy’s amendments would recognize same-sex marriages in which one spouse is an American, and also would allow U.S. citizens to sponsor foreign-born same-sex partners for green cards as long as there’s proof of a committed relationship.

They were among dozens of amendments filed with the Senate Judiciary Committee on Tuesday as the panel prepares to take up the legislation later this week.

“For immigration reform to be truly comprehensive, it must include protections for all families,” Leahy said. “We must end the discrimination that gay and lesbian families face in our immigration law.”

Other amendments proposed by committee members include a proposal by Alabama GOP Sen. Jeff Sessions to significantly cut the number of foreign workers granted admission to the United States under the bill.
