I'm sorry to hear of the trouble these women are experiencing.
If they are being discriminated against because of their race or nationality---as your question suggests, then my advice to each of them, and the avenue for them to seek justice under the laws of the United States would be as follows:
Each of you need to file a formal complaint with the EEOC (Equal Employment Opportunity Commission).
If your company has 15 or more employees, they are prohibited from discriminating against you. To file a complaint with the EEOC, contact the nearest Equal Employment Opportunity Commission field office. To be automatically connected with the nearest office, call(NNN) NNN-NNNN EEOC website: www.eeoc.gov
Federal law specifically prohibits discrimination, based upon the Ethnicity, Color, Religion, National Origin, Age, Sex and Disability of an individual, with regard to hiring, promotion and firing.
After you file the complaint, your employer will be prohibited from any retaliatory action against you. The EEOC will investigate your claim, and 180 days after the filing of the complaint you may ask for a "right to sue letter". The EEOC will issue you the letter which gives you the right to institute a private civil action against your employer and seek monetary damages.
I wish you and your friends the best in 2011.
