It's not a matter of wishing or inventing. Truly, it's a matter of r.e.a.d.i.n.g.:
Federal Law--Section 8 USC 1324(a)(1)(A)(iv)(b)(iii)
A person (including a group of persons, business, organization, or local government) commits a FEDERAL FELONY when she or he: assists an illegal alien she/he should reasonably know is illegally in the U.S. or who lacks employment authorization, by transporting, sheltering, or assisting him or her to obtain employment, or encourages that illegal alien to remain in the U.S. by referring him or her to an employer or by acting as employer or agent for an employer in any way, or knowingly assists illegal aliens due to personal convictions.
