A formal document confirms an individual’s work history, including job title, dates of employment, and sometimes salary information. This documentation is frequently required for visa applications, specifically the H-1B visa, a non-immigrant visa that allows U.S. employers to temporarily employ foreign workers in specialty occupations. For example, it might detail a software engineer’s three-year tenure at a tech company, confirming their experience in a specialized field relevant to their H-1B petition.
Such verification provides crucial evidence for United States Citizenship and Immigration Services (USCIS) to assess the legitimacy of an H-1B application. It corroborates the applicant’s claimed expertise and establishes a credible link between their prior experience and the prospective H-1B employment. This process has evolved alongside changing immigration policies, becoming increasingly vital for ensuring compliance and preventing fraud. Thorough documentation benefits both the applicant and the employer by streamlining the adjudication process and reinforcing the validity of the petition.
