The Border Patrol has launched a major initiative that asks former agents to return to federal law enforcement and help the organization amid mass departures and historically high illegal migration to the United States.

The Border Patrol’s parent agency, U.S. Customs and Border Protection, posted an advertisement on its homepage earlier this week urging agents who are under 40 years of age and quit in the past three years to return to their old jobs, even waiving six-month stints at its academy and offering sizable raises.
