When President Biden entered office in January, with Democratic control of the Senate and House, there was a great deal of hope from left-wing immigration activists that 2021 would be the year in which a broad pathway to citizenship for millions of illegal immigrants would be created and signed into law -- but as the year ends, those hopes have so far been dashed as multiple efforts have hit the rocks.

The Biden administration released a proposal on Inauguration Day, which eventually became the U.S. Citizenship Act of 2021, and was headlined by an 8-year path to citizenship for illegal immigrants already in the country.

It would also grant farmworkers, along with Temporary Protected Status (TPS) and Deferred Action for Childhood Arrivals (DACA), immediate green card eligibility. They would then be eligible for citizenship three years later.

While there was a smattering of security provisions, it was significantly less than seen in past immigration reform efforts -- provisions that were key in getting Republican support. The bill also envisioned processing centers set up in Central America, more immigration judges -- and avenues for legal immigration, including a mass "recapturing" of family and works visas from previous years.

However, with a 50-50 Senate, Democrats recognized that it would need Republican support to gain the 60 votes to overcome the threat of a filibuster. Sen. Bob Menendez, D-N.J., admitted that it would be a "Herculean" task to pass the reform effort.

Sure enough, with minimal border security measures in the legislation and a brewing crisis at the southern border, even Republicans who had supported reform efforts in the past balked -- with Sen. Marco Rubio, R-Fla., calling it a nonstarter.

"There are many issues I think we can work cooperatively with President-elect Biden, but a blanket amnesty for people who are here unlawfully isn’t going to be one of them," Rubio said.

As the bill stalled in Congress, the White House expressed openness to breaking the legislation up into individual pieces that might be able to gain Republican support, with some Republicans having expressed willingness to grant permanent status to DACA recipients.

White House press secretary Jen Psaki told reporters that "Congress will have to work through what it looks like moving forward, and what components will be included here and what components could be dealt with separately."

But as the border surge of 2021 grew over spring and summer, with more than 200,000 encounters a month at one point, there was little sign of a broader Republican appetite for immigration measures that didn’t include border security. And so Democrats tried a different approach.

Build Back Better/budget reconciliation

As Democrats looked for ways to pass sweeping parts of President Biden’s agenda on issues like climate change, family policy and immigration, they eventually zoned in on the budget reconciliation process in order to bypass the Republican filibuster. The budget reconciliation process requires only 50 votes in the Senate, and therefore if all Democrats in the chamber voted in favor, with Vice President Kamala Harris casting a vote as a tiebreaker, legislation would pass the chamber. 

In outlines for the bill were a variety of proposals for amnesty or protections for illegal immigrants, in addition to sweeping changes to legal immigration. The first of those plans would grant a pathway to citizenship for DACA and TPS recipients, farmworkers and those deemed "essential workers." However, that plan was rejected by the Senate parliamentarian in September, who ruled that it was inappropriate for a budget bill as the measure dwarfed its budgetary impact.

Lawmakers then proposed a "Plan B" to update a registry to allow amnesty for illegal immigrants who arrived before 2010 -- which was also rejected by the parliamentarian. Finally, a much more limited Plan C would allow expanded parole powers to grant legal status, including work permits, to an estimated 8 million illegal immigrants for up to 10 years. That too met with the disapproval of the parliamentarian.

Democrats appeared keen to continue, however, with some left-wing Democrats floating the idea of ignoring the parliamentarian altogether. 

MANCHIN DEALS MAJOR BLOW TO DEMOCRATIC EFFORTS TO INCLUDE AMNESTY FOR ILLEGAL IMMIGRANTS IN SPENDING BILL 

But the plan to include an amnesty in the legislation was dealt a major blow in October, when Sen. Joe Manchin, D-W.Va., said that he would not support overruling the parliamentarian and was opposed to any sort of amnesty in the BBB. Without his vote, measures stood zero chance of passing the chamber. 

"For us to even be talking about immigration without border security is ludicrous," he said when asked by Fox News’ Bret Baier if he supported amnesty in the legislation. "I've told them...the average person turns on the TV and sees what's going on in the border, and that basically scares the bejesus out of an awful lot of people," he said. "If [migrants] think they can come and get all the different benefits that people, the citizens of America get are entitled to, they're going to continue to come. So, no, I don't think so."

Manchin would then, in December, deal another blow to the legislation as a whole by saying that he could not support the bill at all.

Going into 2022, activists are certain to continue with their push to obtain various forms of amnesty or legal protection for those in the country illegally, but with a 50-50 Senate still in place and looming midterms that could see Republicans take control in both chambers, it is far from clear whether those efforts will see any success.
