The future for thousands of young people in Massachusetts is unclear after Attorney General Jeff Sessions announced Tuesday that the Trump administration would end the program known as Deferred Action for Childhood Arrivals, or DACA.

"We are people of compassion, and we are people of law," Sessions said in a statement Tuesday. "But there is nothing compassionate about the failure to enforce immigration laws."

DACA granted temporary status to some people whose parents brought them into the country illegally as children. Since then-President Obama initiated the program in 2012, 800,000 eligible recipients nationwide have been able to study and work in the U.S. under this temporary status — including about 8,000 in Massachusetts and close to 15,000 throughout New England.

After receiving deferred action in 2016, Paola was able to begin college studies and receive in-state tuition. At the end of her first day of classes as a freshman at UMass Boston on Tuesday, Paola said she spent much of the day wondering just how long her college experience might last.

"I was obviously trying to focus in class, it's my first day. I want to be able to make sure that I do good, at least for the time that I'm able to go to school," Paola said, sitting among clusters of blue and white balloons and streamers hung to usher in a new school year. "At the same time [DACA] was in my mind because it's like, I'm sitting in a classroom, I'm taking a class right now, but I don't know if that's going to be the story in a year from now."

According to the Department of Homeland Security memo detailing the decision, as of Tuesday the Trump administration will no longer accept new DACA applications. DACA recipients whose temporary status is scheduled to expire before March 5 are eligible for a two-year renewal and must submit that application by October 5. For those recipients whose temporary status is scheduled to expire after March 5, their deferred action will end as of the current expiration date.

Greg Romanovsky, head of the New England chapter of the American Immigration Lawyers Association, says the elimination of DACA will leave most of the recipients with little recourse.

"For the vast majority of the DREAMers there will be no other options. Instead, they will be left completely exposed," Romanovsky said. "All of their information is with the government right now. So the government has the option of actually enforcing their deportation orders or initiating removal proceedings against them."

Romanovsky says it's important to note that DACA recipients were never granted permanent legal status but instead were granted "deferred action" — meaning a temporary suspension of any efforts to have the individual deported.

Critics have long argued that Obama overstepped his authority in establishing DACA by executive order.

"[DACA] was a massive overreach by President Obama. Only Congress has the ability to give immigration benefits to individuals," Andrew Arthur, a resident fellow in law and policy for the Center for Immigration Studies, told WBUR's Radio Boston Tuesday.

Standing alongside Boston Mayor Marty Walsh and Massachusetts U.S. Sen. Ed Markey during a press conference Tuesday, Attorney General Maura Healey said the Trump administration ignored bipartisan calls to keep the program in place.

"My question to the president and to our U.S. attorney general is: Whose side are you on? What does it say about us if we turn our backs on these young people? On these Americans? What does it say if we play politics with their future?"

Healey said she plans to join other state attorneys general in filing a lawsuit against the Trump administration in an effort to protect DACA recipients moving forward. Mayor Walsh said he will work with Healey's office and issued his own statement to Trump and Sessions, declaring that the two are not welcome in the city of Boston.

"This is not enforceable, this is persecution. It's targeting of people, groups of people, not because of what they did but because of who they are," Walsh said.

Republican Gov. Charlie Baker, who recently riled the immigrant advocate community by filing legislation to authorize local law enforcement to honor some detainer requests from U.S. Immigration and Customs Enforcement, also criticized the decision.

"President Trump made the wrong decision today that could negatively impact our economy and many of the Commonwealth's families," Baker said in a statement.

The administration's wind-down of the program allows until March 18 for Congress to pass legislation to protect DACA recipients moving forward. Sen. Markey said Tuesday that he has "a little bit of hope" that Republicans and Democrats may be able to come together and work toward a bipartisan solution.

Back at UMass Boston, Paola says she's trying to stay optimistic.

"This might be the only year that I can go to school and actually be in a class with other students that look just like me but have other opportunities that I don't."
