“I don’t have words to describe how I feel,” Brazil native Thais Marquez, 23, who now lives in Newark, New Jersey, told the crowd. “We don’t know what’s next for our future.”

Among the demonstrators, some of whom gathered at 59th Street and Fifth Avenue shortly before 11 a.m. to march southward to 56th Street, was Luis Chicaiza. A DACA recipient from Hackensack, Chicaiza, 28, said he moved to the United States from Ecuador when he was 10 years old, and he now works at a Cheesecake Factory in New Jersey.

“Without DACA I wouldn’t be able to work, to drive, I wouldn’t be able to do anything,” he said. “We’re not second-class citizens, we are human beings.”

The crowd spoke as one with a chant of “Aqui estamos, y no nos vamos (We’re here and we’re not leaving).”

“DACA wasn’t a gift. There were many brave students who fought hard for this,” said Cata Santiago with Movimiento Cosecha, one of the advocacy groups that organized the demonstration.

Santiago, speaking to rallygoers, said the program has been “life changing” for the 800,000 immigrants who qualified for the program that allowed enrollees to remain in the country to work and study without the threat of immediate deportation. There are 42,000 DACA recipients in New York, according to Gov. Andrew Cuomo.

“It is our job to keep fighting,” Jessica Moreno-Gaicho, a DACA enrollee from Richmond, Virginia, told the crowd. “It is time to fight for all undocumented communities.”

Several of the protesters outside Trump Tower noted that DACA only provided temporary protection for immigrants, and they called on Congress to pass legislation that would offer a more long-term solution for the nation’s estimated 11 million immigrants living here illegally.

Trump’s phaseout of DACA, an Obama-era program created by executive order in 2012, gives Congress six months to come up with an alternative.

“I’m tired of this conditional protection,” said protester Jose Luis Santiago, of Homestead, Florida, and who is a DACA beneficiary. “We’re asking for permanent protection.”

Back on the steps of City Hall Tuesday evening, Cardinal Timothy Dolan and the Rev. Al Sharpton joined de Blasio in a show of support for the so-called Dreamers.

“As a pastor, I can tell you these Dreamers are not criminals, aliens … intruders … they are us, they are our people,” Dolan said. “To demonize them as threats or terrorists contradicts the bible, America, New York and common decency.”

Sharpton recalled Trump’s past efforts to discredit former President Barack Obama’s U.S. citizenship, saying, “You have a president who tried to discredit his predecessor documents … documents [are] not what he’s preoccupied with; bias and division is what he’s preoccupied with.”

De Blasio said the city will “use every legal avenue” to defend New Yorkers affected by Trump’s decision.

“Imagine if you had done things the right way and seen your rights taken away with the strike of a pen,” de Blasio said at the late afternoon news conference. “We are going to stand up to this.”

The mayor urged Dreamers who need legal advice to call 311 and promised those who are feeling unsure about what the future holds that the NYPD would not act a deportation force.

“We are here for you,” the mayor said.

Outside the New York Immigration Coalition’s midtown offices, immigration advocates and local politicians, including city Comptroller Scott Stringer and Public Advocate Letitia James, decried the decision and called on Congress to act quickly.

“I still believe in the dream,” said James, who called the decision to end DACA “blatantly racist.”

Stringer said he’s never been more ashamed of Trump and his administration.

“But make no mistake, we are here today to send a loud and clear message to Congress: You keep this up and you’re going to be on the unemployment line and we will put you where you belong which is out of public life,” the comptroller added.

“That action means that today, Sept. 5, 2017, is going to go down as a dark day in our nation’s history,” said Steven Choi, executive director of the New York Immigration Coalition. “I ask one simple question. How does this decision make America great?”

“How does it make America great to strip this economy of [800,000] workers, to rob this economy of $460 billion in GDP and to tear apart our families and our communities?”

DACA recipient Angie Kim, a 34-year-old organizer at the MinKwon Center for Community Action in Flushing, Queens, was overwhelmed by emotion as she called the Trump administration’s actions “disgusting.”

“I cannot tell you what it means to have DACA,” said Kim, who came to the United States from South Korea with her family when she was 9 years old. “What we can do now is fight back even harder.”

Flor Reyes, a 20-year-old senior at Lehman College, said being covered by DACA gave her a “sense of hope” and inspired her to apply to college.

Reyes broke down in tears as she thought about telling her mother, who has five other children, that she may no longer be able to help her financially.

“To hear we will no longer have this sense of security – it’s scary,” she said. “We just urge Congress to take action.”

Similar protests were held on Aug. 30, when news broke that Trump was considering a repeal of the program, and again on Aug. 15, when the president was in town for meetings.

DACA applies to immigrants who came to the country illegally before their 16th birthday, who were younger than 31 before 2012, haven’t been convicted of a felony or major misdemeanors, and are in school, graduated from school or are honorably discharged veterans of the armed forces or Coast Guard.
