Members of the House of Representatives plan to vote on two immigration reform bills this week as a part of President Joe Bidens sweeping agenda to grant a pathway to citizenship for millions of undocumented people.

The bills are Democrats first attempts to see what progress, if any, they can make on immigration under Biden as a wave of migrants and asylum-seekers, many of them unaccompanied children, arrive at the border.

It has been more than three decades since Congress enacted broad immigration reforms, and anything proposed since then has struggled to gain enough support. Bidens proposed reforms would be the largest legislative overhaul of the U.S. immigration system since Republican President Ronald Reagans administration.

Bidens approach begins with the American Dream and Promise Act, which would provide a path to citizenship for the 2.5 million young undocumented migrants known as Dreamers, as well as the 4000,000 immigrants living in the country with temporary protected status.

The second bill, the Farm Workforce Modernization Act, would allow eligible undocumented farmworkers to apply for legal status and is the biggest legalization effort with broad Republican support.

Both bills passed the House in 2019 but were never taken up in the then-Republican-led Senate for a vote.
