What it means is that illegals will have work permits to waive at employers while citizens will not.
As soon as a couple of citizens file a complaint about being asked for the same kind of permits the feds will rise up against "profiling".
DOJ will, of course, take immediate action.
And documentation will be effectively a moot issue - no one will be willing to check doc's or ask questions.
And, that gets us back to my original supposition: What would an employer then do if presented with a possible illegal applying for a job? Would he, if overwhelmingly against Obama's action, take it out on all hispanics applying for a job? After all, it likely will be next to impossible to tell who is who. There's a simple fix for that.
