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.
