New York City area arrests of immigrants without criminal histories have doubled under President Donald Trump, according to newly released federal data.

Between Jan. 20 and April 29, Immigrations and Customs Enforcement arrested 156 people it deems "non-criminal" in its New York City coverage area, compared with 77 over the same period last year. Arrests of those with criminal convictions increased 19%, from 446 to 531.

A Jan. 25 executive order from the president significantly widened the net of immigrants considered priorities for deportation. The Obama administration had tightened its focus to undocumented immigrants with more serious criminal histories, but Trump's new guidance expands the priority list to include the vast majority of removable immigrants, among them undocumented immigrants who could be charged with any criminal offense, no matter how minor, as well as those who have falsified documents, and certain immigrants with legal status.

A judge struck down the "sanctuary city" provisions of that order but not the enforcement priorities, immigration law professors confirmed.

A regional ICE spokeswoman said that as a matter of practice in New York, those without criminal records, fugitive status or final removal orders are not targeted for enforcement, those that might be arrested if an agent encounters them during an action targeting someone else. This has been practice since the Obama administration but still falls in line with the executive order, the spokeswoman said.

"ICE focuses its enforcement resources first on individuals who pose a threat to national security, public safety and border security," the spokeswoman wrote in a statement. "However, as [Homeland Security] Secretary [John] Kelly has made clear, ICE will no longer exempt classes or categories of removable aliens from potential enforcement. All of those in violation of immigration laws may be subject to immigration arrest, detention, and if found removable by final order, removal from the United States."

Responding to the new data, a spokesman for Mayor Bill de Blasio emphasized the importance of city laws that limit cases in which city jails and police turn immigrants over to ICE. "Any uptick of ICE enforcement against immigrant New Yorkers without a criminal record is a serious cause for concern," he said. "If this is evidence of a shift in enforcement priorities, it serves to further underscore the importance of our sanctuary city policies."

De Blasio said in April that he thought that the changes in ICE priorities had created "tremendous fear" but that "thank God, the actual impact has not been as bad as potentially assumed."

"Much more fear has been created than actual negative impact," he said, but cautioned: "It's early."

The mayor met Monday with Kelly, who in February issued a memo detailing the broadened new enforcement priorities. A readout of the meeting said Kelly "reaffirmed his commitment to enforcement protocols that don’t involve sweeps or visits to hospitals, places of worship, or schools," but did not mention any discussion of increased arrests.
