AbstractUsing the 5% IPUMS version of the 2000 Census, this paper finds that, compared to anotherimmigrant who has a job that requires less human-interaction on a daily basis, an immigrantworker who possesses knowledge in speaking a non-English language and who works in a humaninteraction-intensive occupation would enjoy an average wage benefit of 4.28%. Also, for thosewho work at a job that values language usage and cultural familiarity, immigrants from thesame country of origin are perceived as substitutes, while those from another country would becomplements, a finding that is in accordance with the standard labor supply theory, holdingdemand constant. Moreover, a one standard deviation increase in bilateral trade volume betweenthe United States and the immigrant's country of origin is predicted to enhance the immigrant'sreturns to working in the Wholesale Trade industry by 3.36% on average, a pattern that is verydifferent for immigrants who came from a country that uses English as an official language.
