President Donald Trump has already signed a series of executive orders related to changing how immigration works in the United States. NY1 learned mass deportation raids are expected to take place in New York City shortly, as part of the larger efforts the president campaigned on.

Shortly after getting sworn in as the 47th president of the United States, Donald Trump announced in his inauguration speech his first course of action would be about immigration.

“I will declare a national emergency at our southern border,” he said, which was followed by a long ovation.

The president declared a national emergency in his first term, allowing him to unlock billions of dollars in funding for building the border wall he has long promised.

The difference this time? He did it on day one. Last time was more than two years in.

The crackdown at the southern border has already begun. The app created by the Biden Administration, CBP One, which allowed one million migrants to schedule interviews with Customs and Border Patrol and apply for asylum at the southern border, has been shut down.

It left migrants waiting for their appointments with no path in now.

President Trump also pledged to bring back the return to Mexico policy, which would force asylum seekers to wait in Mexico for their hearings in our immigration courts. There would need to be coordination and cooperation with Mexico for this to occur.

All of this could mean fewer people coming from the southern border to New York City.

Additionally, in an interview after the inauguration, Rep. Nicole Malliotakis confirmed mass deportations will occur very soon in New York City.

“I met with [Immigration and Customs Enforcement Director] Tom Homan a couple weeks ago," she said. "Chicago is first, but New York will be right after that. So, I don’t know exactly how many days it will take."

When asked to clarify if she expects New York to be next, she said, "yes."

She elaborated on who she expects the raids to target.

“It’s focused on criminals. They are focusing on the cartels, the gang members, the sex traffickers, on the drug traffickers," she said. "They want these dangerous people in this country removed. And so do my constituents.”

But mass deportations are something deeply unsettling to Donna Lieberman, the executive director of the New York Civil Liberties Union. She said she fears who will actually end up being detained.

“It’s scary to have an arm of government be such a threat, but it is and there are a lot of good people and families, many of which have people of mixed status that are very worried right now,” she said.

A church on the Upper West Side already has a sign saying ICE is not welcomed.

Right now, there is an ICE policy in place that effectively prevents federal agents from going into a church to conduct a raid. It would require very specific circumstances and approvals for it to be allowed.

However, it has been reported that President Trump is considering revoking that policy, which would simply require an updated memorandum by ICE, according to multiple immigration experts NY1 has consulted with.

Trump also signed an executive order to end birthright citizenship. It’s part of the 14th Amendment that goes all the way back to reconstruction, saying that anyone born in the any of the 50 states and almost every U.S. territory -- no matter their parents’ status -- is a citizen. 

That would require a constitutional amendment, meaning two-thirds of congressional support in both chambers and then 75% of state legislatures adopting it as well.

It is expected this executive order, among others signed, will be challenged in the courts as well.
