The most common industries for immigrants in the US to work in are the educational and health services, which the Census Bureau groups together, and the professional and business services industries. These are also the largest industries overall in the US. The industry with the largest amount of immigrant workers relative to its overall size is construction.
The Census Bureau uses the North American Industry Classification System (NAICS) to categorize broad industries and the sub-industries that fall under them.[1] For example, professional services include legal and accounting services; educational services include roles at primary and secondary schools, colleges and universities, and trade schools; and health services include the work of physicians, nursing care facilities, and child care, among others.
