From the Oregon Employment Department:
The Employment Department is an equal opportunity agency and does not discriminate in providing services on the basis of race, color, religion, sex, nation of origin, age, disability, political affiliation or belief, citizenship, or marital status.
Apparently they offer equal opportunities to people who have broken our immigration and labor laws. Violate the employment laws all you want, the deparment charged with enforcing them simply doesn't care!
For those of you who read my site and don't speak English, the state offers employment info on Spanish only pages as well:
