Tomorrow you should call Arlen Specter's Judiciary Committee Office ((202) 224-5225) and tell him you are opposed to his proposed "gold card" immigration legislation. NAOC has more on the legislation itself and what to say. Among other things, the legislation proposes to give immigrants a "gold card" enabling them to stay in the country as long as they are working but not putting them on any kind of path to obtain a green card.
My friends in the know say this: "Specter is still mainly hearing from rabid anti-immigrant zealots, and he's actually movable if he hears enough from level-headed folks. Everything we're hearing from our DC allies is that personal calls are making a significant difference."
