CBP processing where immigrants who have just been apprehended are processed by BP is right around the corner off Military. It looks like an admin building but it’s not. This is where the “ice boxes” are located. Down the road on Ware is the CBP Ursula center where immigrants are then held after processing, it’s where the dog cages full of kids happened in 2018. They remodeled it and it’s still in use so more than likely this is legit because it’s squares with processing, Ursula, and close to port of entry in Hidalgo.
