To be more accurate, it is amnesty to guest worker, which was the Bush Plan, as opposed to amnesty onto the path, which was McCain Kennedy.
The third type of amnesty is the Pence Plan, which the Gang of 12 adopted in 2007, which is touch-back amnesty.
No real difference. Amnesty is amnesty.
There is a difference, but in this case it is truly amnesty to the path, because the 5-year clause makes them eligible for citizenship.
If it was three years, and included a provision that excluded them from citizenship, then it would be the “guest-worker” provision, rather than an amnesty-citizenship provision.
