NEW YORK — Single adult migrants will only be able to stay in New York City shelters for 30 consecutive days under a new policy Mayor Eric Adams announced Friday amid a ongoing influx of asylum-seekers.

The policy, which takes effect immediately, means all single adult migrants who apply for shelter will receive notices upon being accepted for placement informing them they have 30 days before vacating their beds. According to Adams’ office, migrants who get 30-day notices will also receive “intensified casework services” aimed at helping them find their own housing, in New York or elsewhere.

If they can’t find new housing within the 30-day window, migrants can come back to the Adams administration’s asylum-seeker arrival center at the Roosevelt Hotel and reapply for another monthlong shelter stay, a City Hall official said. Single adult migrants who are already in the city’s care will start receiving 30-day notices, too, the official said.

The timing of the new policy comes a day before migrants who have received 60-day notices two months ago are required to go back to the Roosevelt Hotel to reapply for shelter.

The new restriction comes as more than 60,000 migrants, most of them from Latin America, remain in city-run shelter and emergency housing facilities. Hundreds more migrants continue to pour into the city every week, and Adams said in a statement that he has to enact policies like the 30-day shelter stay limit in order to free up shelter space for new arrivals.

“With more than 60,000 asylum-seekers still in our care and without additional help, we will be forced to continue making difficult decisions,” said Adams, who has for months pleaded for more help from the federal government and New York Gov. Kathy Hochul’s administration.

Migrant families with children are not impacted by the restrictions and can stay in city shelters as long as they need. However, city government sources familiar with the matter told the New York Daily News earlier this week that the Adams administration is considering placing limits on how long asylum-seeking families with kids can stay in shelters, too.

The new policy is an escalation of a practice the administration enacted this past summer that limited consecutive shelter stays for single adult migrants to 60 days.

According to Adams’ office, city workers have handed out about 13,000 60-day notices since that policy took effect about two months ago.

The first batch of 60-day notices issued by the city are set to come due Saturday. Advocates have raised concern that the shelter stay limits are going to result in migrants sleeping in the streets, and the Roosevelt Hotel asylum-seeker arrival center could see droves of asylum-seekers show up Saturday to reapply for shelter.

On Wednesday, the Biden administration announced the U.S. is extending a form of protected status for Venezuelan migrants that’ll put them on a fast track to work permits — a move Adams had requested from the feds for months as a means of allowing new arrivals to contribute to the local economy.

Thousands of Venezuelan migrants in the city are expected to be able to benefit from the expedited work permits.

But a City Council source, who requested anonymity out of fear of angering the mayor, predicted the new 30-day shelter stay limit could prove problematic for migrants seeking work authorization because change of addresses would almost certainly slow the flow of their application paperwork.

“It increases the likelihood there will be problems because their mailing addresses will change,” the source said.
