Vance Air Force Base isn’t the only Oklahoma military installation that has caught illegal immigrants trying to enter. Altus Air Force Base has had three incidents within the past 27 months in which eight undocumented workers attempted to gain access as contractor employees to work at sites there, said Lisa Holland, acting chief of public affairs at the base. "These undocumented workers were detained and turned over to the Altus Police Department who then coordinated with Immigration Customs Enforcement for further action,” Holland said.
At TinkerRon Mullan, spokesman for Tinker Air Force Base, said that base’s security screening process identified one employee of a subcontractor with an invalid ID within the past year and that worker was denied base access. "Tinker has badging procedures in place to ensure identification of contractor employees,” Mullan said. John Long, public affairs officer at Fort Sill in Lawton, said he was not aware of any similar incidents there.
