SO MANY PLANS, SO LITTLE TIME. For those of you confused by the various plans out there (at last count, there are no fewer than eight, and at least four are seriously being considered), this side-by-side comparison (PDF) from the nonpartisan Migration Policy Institute is the best summary you'll find. Remember, too, that guest-worker programs don't just come in terribly bad and pretty bad flavors; the McCain-Kennedy plan offers so many routes to citizenship that their guest-worker program isn't too bad at all, though I'd prefer the path to citizenship be activated instantly after hire.
