If you are seeking to come to the U.S. for employment as a temporary worker in the U.S. (H, L, O, P, Q and R visas), your prospective employer must file a petition with the Department of Homeland Security (DHS), United States Citizenship and Immigration Services (USCIS). This petition must be approved by USCIS before you can apply for a visa. Select temporary workers to visit the USCIS website and learn more about requirements. For questions related to petition approval, you may contact USCIS at 1-800-375-5283.
