A man was stabbed in the back outside a migrant reprocessing center on the Lower East Side early Sunday — just the latest violence around the city’s asylum-seeker sites, police and law-enforcement sources said.

The victim, whose last known address was in Queens, is in stable condition and expected to survive, they said.

It wasn’t immediately clear what caused the Manhattan violence or whether the stabbed man or his assailant is an asylum-seeker.

The bloodshed occurred around 12:30 a.m., but police didn’t learn about it till hours later because afterward, the victim took private transportation to the vicinity of the 105th Precinct station in Queens, where he eventually spotted an officer and said he had been stabbed, sources said.

The man was then rushed by EMS to North Shore University Hospital in Manhasset.

No arrests have been made in the attack, which occurred outside the former St. Brigid Elementary School building on East Seventh Street during a dispute, cops said.

The site is where migrants can reapply for more free city housing after they already go through a stint in the groaning shelter system.

Migrant facilities have been the scene of three other stabbings in just two weeks, an alarming trend that has prompted officials to begin installing security cameras and weighing metal detectors.
