Immigration courts reopened Friday, but it’s unclear how hearings canceled during the shutdown will be rescheduled.

A spokeswoman for the Department of Justice, which oversees immigration courts, said cases will be rescheduled based on the availability of immigration judges. But immigration attorney Jeffrey Feinbloom said there are problems with that plan.

“These are very, generally speaking, particularly in New York, very busy and often over-worked judges,” Feinbloom said. “And they have crowded calendars, and I really don’t know how that’s going to play out.”

In New York State over 50,000 cases are currently pending, and judges already have hearings scheduled in 2017.
