Persons going to the United States with the intention of working there temporarily require a nonimmigrant work visa. Persons entering the United States on a visitor or business visa, or under the Visa Waiver Program are not permitted to work.

The United States does not issue work visas for casual employment. In general, work visas are based on a specific offer of employment from a U.S. employer.

The most common categories of nonimmigrant work visas are:

• Temporary Work Visa (H) - This visa is for prearranged professional or highly skilled employment for a temporary period, or to fill a temporary position for which there is a shortage of U.S. workers, or to receive training from an employer. The employment or training must be approved in advance by United States Citizenship and Immigration Services (USCIS) in the United States on the basis of an application filed by the prospective employer.

• Intra-company Transferee Visa (L-1) - The visa allows a multinational business having offices in several countries to transfer managerial and executive personnel to the United States. The employer must first receive an approval from USCIS in the United States for the transfer of the employee before a visa application can be submitted. Details...
• Treaty Trader/Investor Visas (E -1 and E-2) - This visa is required by a national of a country with which the United States maintains a treaty of commerce and navigation who wishes to go to the United States: to carry on substantial trade, including trade in services or technology, principally between the United States and the treaty country; or to develop and direct the operations of an enterprise in which the national has invested; or is in the process of investing a substantial amount capital.

• Treaty Aliens in Speciality Occupations (E -3) - This visa allows for the temporary entry into the United States of individuals who are to perform services in a specialty occupation for a U.S. employer.

The U.S. employer is required to file a Labor Condition Application (LCA) with the Department of Labor. The applicant will be required to furnish the original approved LCA at the time of applying for the visa. Details...
