touchback

touchback
 n.— «In addition, undocumented immigrants who have been in the United States for two to five years, no matter where they live, would have to travel back to a port-of-entry on the U.S. border, such as El Paso, Texas, and go back across the border to apply for guest-worker status. Upon performing this so-called touchback, these several million immigrants could immediately return to their U.S. homes.» —“Critics: Immigration bill bordering on unrealistic” by Frank James Chicago Tribune Apr. 17, 2006.
