Perhaps you should understand the law before you post snarky comments accusing people of breaking the law. Here are the relevant exceptions to the law, from the source:

"(A) a person or other entity that employs three or fewer employees,

(B) a person’s or entity’s discrimination because of an individual’s national origin if the discrimination with respect to that person or entity and that individual is covered under section 703 of the Civil Rights Act of 1964 [42 U.S.C. 2000e–2], or

(C) discrimination because of citizenship status which is otherwise required in order to comply with law, regulation, or executive order, or required by Federal, State, or local government contract, or which the Attorney General determines to be essential for an employer to do business with an agency or department of the Federal, State, or local government."
