A U.S. Work Visa allows individuals to enter the United States temporarily for employment under a specific employer and job position approved by U.S. authorities. Most work visas, such as H-1B, L-1, P3 or seasonal categories, require a petition filed by the U.S. employer and approved by USCIS before the applicant can apply at the Embassy. Applicants must demonstrate the necessary qualifications, skills, or experience for the offered position, as well as compliance with all labor and immigration regulations. After the petition is approved, the applicant completes the DS-160 form, pays the visa fee, and attends a consular interview. Work visa holders must maintain their employment status and intend to depart the United States once their authorized work period concludes.
