The U.S. Army has stopped discharging immigrant recruits who enlisted seeking a path to citizenship — at least temporarily.

A memo shared with The Associated Press on Wednesday and dated July 20 spells out orders to high-ranking Army officials to stop processing discharges of men and women who enlisted in the special immigrant program, effective immediately.

It was not clear how many recruits were impacted by the action, and the Pentagon did not immediately respond to requests for comment about the memo.

“Effective immediately, you will suspend processing of all involuntary separation actions,” read the memo signed by Acting Assistant Secretary of the Army for Manpower and Reserve Affairs Marshall Williams.

The disclosure comes one month after the AP reported that dozens of immigrant enlistees were being discharged or had their contracts cancelled. Some said they were given no reason for their discharge. Others said the Army informed them they’d been labeled as security risks because they have relatives abroad or because the Defense Department had not completed background checks on them.
