The National Council of La Raza's opposition to the Immigration Reform and Control Act of 1985 (S. 1200) is explained in this paper, which was presented as testimony before the Senate Subcommittee on Immigration and Refugee Policy. Three provisions of the proposed bill are analyzed: employer sanctions, legalization, and guestworkers. First, the paper asserts that employer sanctions would lead to increased employment discrimination against Hispanics, and that, furthermore, S. 1200's omission of a uniform verification process and strong, effective anti-discrimination provisions would undermine the bill's effectiveness and political viability. The targeted enforcement of existing labor laws is proposed as a better deterrent to the hiring and exploitation of the undocumented. Secondly, it is predicted that, even if S. 1200's proposed "triggered" legalization program were implemented, it would not substantially reduce the undocumented population. It is proposed that the legalization program be restructured along the lines of the Roybal bill (H.R. 4909). Third, La Raza's opposition to the expansion of guestworker programs is clarified. The importation of large numbers of foreign workers, it is argued, is inimical to the legislation's supposed purpose of protecting domestic jobs and may actually encourage illegal immigration. Other problems with S. 1200 are outlined, and implications of data regarding the general public's ambivalence to immigration issues are discussed. Four attachments, all originating with La Raza, provide research findings that support the paper's major points. (KH)
