Why are not all States routinely checking for citizenship status?

We dont bother much with checking peoples citizenship in Australia. There are exceptions of course, with say, seasonal workers picking fruit, or any other unusual activity. From what I have read on My Lot, the US has great need to check citizenship of a LOT of people, most of whom should be deported. Guess you better start a campaign to have this check more frequently.

Im not sure why more states dont do this. But i think its good that arizona is doing it. Other states probably arent doing it because it would take too much of their time up.

I think the main reason is that police are often over-burdened. While border states tend to have high numbers of illegal immigrants, illegals will keep moving to find work. And current law allows children born in the United States to be granted automatic citizenship. I found this great article about a movement to eliminate that loophole: http://www.phxnews.com/fullstory.php?article=54834. The only way that they could do this is to decrease funding to the war (no political comments please, hear me out!) and turn that back into paying for additional police to check everyone's citizenship (but hey, what about lost children? They don't carry around ID). It would probably become a police state here in the US--what a mess.
