Have you seen
H.R. 3534 (introduced by Rep. Tom Tancredo)? We need to support this bill by writing our Congresscritters instead of wasting our breath complaining about Bush's plan. Bush knew his plan wasn't going anywhere, it was part pandering and part throwing down of the gauntlet to Congress to take action...IOW, all politics.
I think there is much to consider regarding the Tancredo plan.
When and if they sit down in committee and begin work on this, rather than posture, I am sure these code changes will get attention.
