How was immigration to United States limited

Immigration, perhaps more than any other social, political, or economic process, has shaped the United States as a nation. The immigration-driven transformation of the country's economic and social landscape has previously occurred during distinct historical periods.

Large-scale immigration resumed in earnest in the 1970s and has continued steadily until the recent recession. The recent change in immigration flows has been marked by a slowing of illegal immigration and of employer demand for foreign high-skilled workers.

The recession has also diminished a sense of urgency to enact immigration reform legislation. President Barack Obama is on record with a commitment to immigration reform, but he did not place it in his top tier of legislative priorities for the first year of his new presidency.

To date, the Obama administration has implemented new strategies for carrying out its immigration enforcement responsibilities regarding employers, detention, and criminal aliens. It has also emphasized naturalization and modernized systems that support legal immigration. Finally, it has broadened border control efforts to emphasize not only immigration but also joint efforts with Mexico to reduce arms trafficking and drug-war violence.

This profile examines major legislation and events affecting U. S. immigration, the size and attributes of the immigrant population in the United States, legal and illegal immigration streams, U. S. policies for refugees and asylum seekers, the impact of the recession on immigrants and immigration, immigrant integration efforts, recent immigration enforcement trends, and prospects for comprehensive immigration reform legislation.
