In the American history the last decade of the 20th century was characterized by the increase in the numbers of immigrants coming to the US. At first, unfavorable economic circumstances led to an increase in nativism intensifying the debate over the short-run economic effects of the generous immigration policy continued by the United States. Present methodology (abstract models, statistical analysis, and cross-sectional studies) is insufficient to give a definitive estimation of immigration impact on unemployment, wages and public funds, therefore these questions are still easily manipulated by the supporters as well as the opponents of the current American immigration policy. We can assume that a net economic benefit is so small that policymakers will have to find another reason to maintain the 'open door' policy.
