In order for you to come to the United States lawfully as a nonimmigrant to work temporarily in the United States your prospective employer must generally file a nonimmigrant petition on your behalf with USCIS¹.   The main nonimmigrant temporary worker classifications are listed in the table below. For more information about the filing requirements for particular nonimmigrant classifications, see the specific classification links under “Temporary Workers” to the left.

Spouses and Children Seeking Dependent Nonimmigrant Classification

Spouses and children who qualify for dependant nonimmigrant classification of a temporary worker and who are outside of the United States should apply directly at a U.S. consulate for a visa.
Spouses and children requesting a change of status or extension of stay in a dependent nonimmigrant classification must file Form I-539, Application to Extend/Change Nonimmigrant Status.  Please see the Form I-539 instructions for further information on filing procedures for this application.
