You err seriously in running these two things together. Nothing wrong with a guest worker program as long as 1) it doesn't apply to any illegal currently in the US, 2) can only be applied for from the prospective guest worker's home country, 3) is for a limited time period, 4) "birthright citizenship" does NOT apply to any children born to the "guest worker" during that time, and 5) offers NO path to citizenship.
The thing that is anathema is any sort of amnesty that offers any kind of path to citizenship or permanent residency.
You may think I err seriously but anything other than the plan you detailed would be a form of amnesty.
Since we all know that the plan you detailed is not one they'd ever have the guts to pass I don't consider myself in error.
