text: where are the best spots to go through when coming into the us illegally from mexico? this is the official walkthrough guide on how to enter the us illegally without getting caught. well you could try the desert but you probably wouldnt survive.  my suggestion is goto the us customs office and then...run!  just try not to get shot at.  alternatively goto tijuana, go to the beach, swim for about 30km and then go back to the beach and ask someone "wheres my towel gone?"  alternatively, fedex yourself.
