This is law enforcement. They will plead guilty to the transgression of being here illegally by paying a fine. The fine is the sentence for the transgression. At that point, they are permitted to apply to remain.
And all this is so only if they have a job. If they do not have an employer, they may not apply.
This policy is excellent.
Yes, and the illegals who apply for the blue card end up exposing their employer. What a concept!
