The U.S. Border Patrol's Del Rio sector is among those bracing for sequester's across-the-board federal cutbacks about to hit next month.
Rodolfo Karisch, the sector's chief agent, said his agents still have a jobs to do.
"It's not just about protecting the border, it's about protecting and saving lives," Karisch said.
He said the last year saw more activity than in 2011, 21,720 apprehensions, 29 deaths and seven rescues.
Karisch said already this year, his agents have rescued seven immigrants.
Predictions are it may be even busier this year.
But now with looming furloughs and reduced overtime for his 1,600 agents, Karisch said, "We're going to have to adjust, but it doesn't mean we're going to be prevented from doing our job."
Karisch said they will be relying on "force multipliers."
He said, "Often times, you don't strictly need just manpower, if you have technology."
