The Feds take out one page newspaper ads in Mexican, Phillipine, Salvadoran, Guatamalen, etc. national newspapers.

The bulk of the ad is a picture of a much-worse-than-Manzanar-like camp. With the words "Be warned, if you come to the US illegaly, this is where you will live, this is where we will put you for an indefinite period of time, no e-mail, wire transfers or phone calls. If you want to come to the US illegaly, this is what you will get - you have been for-warned."
