We have laws. Enforce the laws. We have laws for theft, they are enforced. We have laws for people crossing the border illegally. Enforce them.
Many employers have no idea that people that they hire are illegal. Fill out the I9, take all relevent information, call in to the INS hotline and the SSN is good. Except for one little problem..it's someone else's SSN.
If the border were enforced this discussion is moot.
Steal documents from National Archives.....unless your Sandy Berglar covering up for Clinton, the laws will be enforced. /sarc
We should be able to put together an employer funded ($ per entry) Federal database with enough general descriptive information (gender,age,state of residence [not seen by employer]), to at least trigger "Requires Further Confirming Data", in response to descriptive data first entered by the employer. This would trip up the vast majority of the illegals.
Then, the now "unconfirmed" applicant would be required, at their expense (at the same type of automated fingerprint vendors currently doing this for teacher and other applicants) to submit their fingerprints so that Federal investigators can quickly and efficiently make a comparison with the SSN holder of record (this isn't really going to happen, unless there is a legitimate problem, because the illegal will never go to the automated fingerprint collection vendor).
BTW- Three things in order to prevent a conspirator employed at an employer's HR office from running SS numbers until they get an acceptance 1)Charging for each query, with an auditable Federal report back to the employer. 2) A requirement that a completed employment application (whether eventually employed or not) be kept on hand for a specific time (forcing a complete application for each SSN query). 3)Strict penalities for attempting to beat the system. If employers don't like to do it? Allow commerical vendor's (like those currently taking teacher etc. prints) to qualify people.
