Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a nonimmigrant visa for temporary stay, or an immigrant visa for permanent residence. Temporary worker visas are for persons who want to enter the United States for employment lasting a fixed period of time, and are not considered permanent or indefinite. Each of these visas requires the prospective employer to first file a petition with U.S. Citizenship and Immigration Services (USCIS). An approved petition is required to apply for a work visa.

Labor Certification

Some temporary worker visa categories require your prospective employer to obtain a labor certification or other approval from the Department of Labor on your behalf before filing the Petition for a Nonimmigrant Worker, Form I-129, with USCIS. Your prospective employer should review the Instructions for Form I-129 on the USCIS website to determine whether labor certification is required for you.

Petition Approval

Some temporary worker categories are limited in total number of petitions which can be approved on a yearly basis. Before you can apply for a temporary worker visa at a U.S. Embassy or Consulate, a Petition for a Nonimmigrant Worker, Form I-129, must be filed on your behalf by a prospective employer and be approved by USCIS. For more information  about the petition process, eligibility requirements by visa category, and numerical limits, if applicable, see Working in the U.S. and Temporary (Nonimmigrant) Workers on the USCIS website. Once the petition is approved, USCIS will send your prospective employer a Notice of Action, Form I-797.

How to Apply

After USCIS approves the Petition for a Nonimmigrant Worker (Form I-129), you may apply for a visa. There are several steps in the visa application process. The order of these steps and how you complete them may vary at the U.S. Embassy or Consulate where you apply. Please consult the instructions available on the embassy or consulate website where you will apply.
