In the Rio Grande Valley, agents have space to temporarily house 3,400 immigrants at nine stations and a massive central processing center.

Due to a lack of longer term detention space, which is run by Immigration and Customs Enforcement, many families would be released with ankle monitor and notices to appear in immigration court, Ortiz said.
