Using data from the 1988 National Educational Longitudinal Study, examines postsecondary enrollment decisions of immigrant students. Finds that first- and second-year generation Asians are significantly more likely to enroll in both 2- and 4-year public colleges and universities, whereas second-generation Hispanics and native blacks have a higher probability of enrolling in both public and private 4-year colleges and universities.
