Bush's Guest Worker Program has a five year residence permittence. That alone sinks it as far as I am concerned. Get out of America and apply to re-enter is the only terms that I believe in. Harsh?

But doesn't "residence" mean that, after that time period expires, they either "re-up" or go back to Mexico?

As I understand it, the program does not lead to a Green Card.

they either "re-up"

Or drop an anchor baby and ask to stay to protect the new American citizen.
