Please call your Senators and tell them to oppose S. 1348, the Kennedy-Bush immigration plan (aka "the Kennedy-Bush amnesty plan").
The number for the Senate switchboard is 202-224-3121.
You can also find the numbers of your Senators and Congressmen by clicking on this link (listed alphabetically by last name).
It doesn't hurt to pre-emptively call your (House of Representatives) Congressmen as well, and tell them to oppose whatever the House version of the bill is if S. 1348 passes.
That is all.
