If you are outside of the United States you must apply for a visa upon approval of a petition. You may then use the visa to seek admission to the United States as a non-immigrant (temporary). If you are already in the United States, you may be able to apply for a change to the correct non-immigrant (temporary) classification, or for an extension of a prior period of admission. If you are not in a valid non-immigrant status or have not continuously maintained your status, your application for change of status or extension of stay may be denied, and you may need to go abroad to apply for a visa upon approval of the petition.
The Immigration and Nationality Act provides several categories of non-immigrant visas for a person who wishes to work temporarily in the United States.
