Efficacy of US Immigration Policies: What Do Available Evidence Suggest?

This paper tries to gather available evidences pertaining to the potential effects of changes in immigration policies of United States of America (USA), the top global emigrant destination. USA government seems to go ahead with restrictions on emigration to USA. In this context, this paper attempts to examine the efficacy of such curbs using available historical and empirical evidence. It is important to gather evidence pertaining to potential impact of such curbs as they are likely to depress global emigrant flows considerably. This is likely to induce negative shocks on nations who send large number of emigrants (for ex: India). The paper is expected to provide some information regarding the historical/empirical evidence pertinent to actual association between immigration policies and immigration so that stakeholder community of emigration systems of these nations can be more realistic in their approach towards immigration curbs in USA and other major destinations.
