Marion Graham, a United States citizen, (petitioner) submitted an application for labor certification for Gladys Yolanda Ulloa, an immigrant, for a live-in housekeeper position. On the application, Graham described the various duties required for the position. One of the conditions of employment was that the housekeeper had to live in Graham’s home. The Department of Labor denied Graham’s application on the basis that the live-in requirement was unduly restrictive, and thus in violation of 20 C.F.R. 656.21(b)(2), which requires that employers wishing to hire aliens on a permanent basis list the potential job without unduly restrictive requirements. Under the statute, a requirement that a worker live on the employer’s premises is presumed unduly restrictive. To overcome this presumption, the employer must demonstrate that the requirement arises from a business necessity. In a letter of rebuttal, Graham argued that her live-in requirement did in fact arise from a business necessity. The Department of Labor nevertheless issued a final determination denying the application, and Graham appealed to the Board.
