Depending on your employment situation, many options are available for non-citizens to work in the United States. Eligible categories include skilled professionals (H-1B), temporary or seasonal workers (H-2), intra-company transfers (L-1), treaty investors (E-2), outstanding scientists/artists/athletes (O-1), and exchange visitors (J-1). Most employment-based non-immigrant visas allow options for children and spouses to accompany.
