Economic theory suggests that an increase in the supply of labor will reduce the wage for all workers (native and immigrant). This paper uses aggregate data to examine the effect of increasing share of immigrant worker on relative wage level. Pooling the Scientists and Engineers Statistical Data System Surveys in 2003, 2006 and 2008, the OLS result suggests that increasing share of immigrant worker has a negative effect on wage for all workers. The estimates suggest that an additional percent increase in immigrant share within the occupation will lower the annual median salary by $220.50 if other things being equal. And the higher degrees the workers receive, the lower the immigration will affect their wage. However, the estimates are not statistically different from zero.
