Can you tell me about the non-immigrant temporary US work visas?

The United States has many non-immigrant temporary work visas to legally live and work in the US for initial periods of up to 12-60 months. The amount of time that a foreign worker will be authorized to live and work in the US will be determined by the visa type and other factors. Each temporary US work visa program has its own eligibility requirements, procedures and benefits. Non-immigrant US work visas usually have an option for the foreign worker’s legally married spouse and unmarried children under 21 years of age to also live in America with the relevant family visa. Many non-immigrant temporary US work visas have an option to be renewed/extended if the foreign worker meets the criteria. Examples of non-immigrant temporary US work visas include the E2 Visa (for treaty investors); H1-B Visa (for specialty occupations); L-Visas (for intracompany transferees); O-Visas (available to foreign workers with extraordinary abilities/achievements); P-Visas (for internationally-recognized athletes, performers, artists, and entertainers); and the R1-Visa (for temporary religious workers).
