The purpose of this study is to analyze the relationship between economic growth, capital, labor and migration in the USA by using the COBB-Douglas production model. In the study, the stationarity of the variables was examined first. A cointegration relationship was found between the variables through the ARDL estimates, based on empirical evidence. In the final stage of the empirical analysis, the causality relationship between the variables was analyzed by the VECM Granger causality test. A two-way causality between capital and economic growth was found. In addition, a unidirectional causality from migration to economic growth and from economic growth to labor was identified. It is concluded that migration is a factor that stimulates the US economy, and the policies that policy makers will implement for migrants will guide the country's economy in the short-term and long-term.
