The Biden administration on Monday renewed efforts to shield hundreds of thousands of immigrants who came to the United States as young children from deportation, the latest maneuver in a long-running drama over the policy's legality.

The administration proposed a rule that attempts to satisfy concerns of a federal judge in Houston who ruled in July that the Deferred Action for Childhood Arrivals program was illegal, largely because the Obama administration bypassed procedural requirements when it took effect in 2012. The new rule mirrors the Obama-era initiative, recreating the 2012 policy and seeking to put it on firmer ground by going through the federal regulatory process.

U.S. District Judge Andrew Hanen, an appointee of President George W. Bush, said the Obama administration overstepped its authority and did not properly seek public feedback. He allowed for renewals to continue but prohibited new enrollments. The Biden administration is appealing.

The 205-page proposal solicits public feedback to address Hanen's concern, though it is unclear if that would be enough. The proposed regulation will be published Tuesday in the Federal Register, triggering a 60-day comment period and ensuring that it is unlikely to take effect for several months.

The office of Texas Attorney General Ken Paxton, who challenged DACA with eight other states before Hanen, did not immediately respond to a request for comment.

The Obama administration created DACA with a memo issued by then-Homeland Security Secretary Janet Napolitano. It was intended as a stopgap measure until Congress legislated a permanent solution, which never occurred.

And because DACA isn't the product of legislation, it falls into a category of policies that can more easily be changed from one administration to the next. President Donald Trump tried to rescind the DACA memo and end the program, but the Supreme Court concluded he did not go about it properly.

In attempting to shore up DACA through a formal rule — which is a more rigorous process than the original memo, though still not legislation — the Biden administration hopes to gain a legal stamp of approval from the courts.

It seems possible, if not likely, that the Supreme Court will once again be called upon to weigh in, unless Congress acts first.

The Biden administration's move comes as congressional Democrats struggle to include immigration provisions in their 10-year, $3.5 trillion package of social and environment initiatives. Language in that bill helping millions of immigrants remain permanently in the U.S. has been a top goal of progressive and pro-immigration lawmakers, and Democrats cannot afford to lose many votes.

But the Senate's nonpartisan parliamentarian said earlier this month the immigration provisions couldn't remain in the sweeping bill because it violated the chamber's budget rules.

Homeland Security Secretary Alejandro Mayorkas called again on Monday for Congress to act swiftly to provide "the legal status they need and deserve."

"The Biden-Harris Administration continues to take action to protect Dreamers and recognize their contributions to this country," said Mayorkas, using a commonly used term for immigrants who came to the U.S. with their parents as young children. "This notice of proposed rulemaking is an important step to achieve that goal."

Some pro-immigration advocates echoed Mayorkas' view that the onus is on Congress.

"A more formalized version of DACA will stabilize the lives of DACA-eligible Dreamers but legislative action is still needed to fully solidify DACA recipients' contributions, expand protections to other Dreamers and build a pathway to permanent legal status," said Ali Noorani, president of the National Immigration Forum. "Formalizing DACA is a positive step, but it's not a permanent fix."

The Democratic-run House passed legislation earlier this year creating a way for Dreamers to become legal permanent residents, but the bill has gone nowhere in the Senate, where Republicans have blocked it and bipartisan talks have stalled. The Senate parliamentarian's ruling further dampened legislative prospects. Advocates have said they would present alternative immigration provisions in hopes they would be permitted in the bill, but it's not clear that would succeed.

Stephen Yale-Loehr, a professor of immigration law practice at Cornell Law School, said the administration's proposal carries no major changes and "is an effort to bulletproof the existing program from litigation challenges."

The proposal adheres to the same criteria, which include arriving in the country before age 16, continuously residing in the United States since arrival and being in the country on June 15, 2012.

Since 2012, more than 825,000 immigrants have enrolled in DACA.
