The United States Citizenship and Immigration Services (USCIS) reviews an applicant’s work history when adjudicating H-1B visa petitions. While there’s no explicitly stated timeframe for how far back this review extends, USCIS officers scrutinize the provided documentation to verify the legitimacy of claimed experience and assess the applicant’s qualifications for the specialized occupation. This commonly involves examining resumes, employment letters, pay stubs, and potentially tax returns. For example, an applicant claiming five years of experience might be required to provide supporting documentation for each of those years. This scrutiny serves to ensure the applicant possesses the skills and experience necessary for the position.
Thorough vetting of employment history is crucial for maintaining the integrity of the H-1B program. It helps prevent fraud and ensures that only qualified individuals are granted visas. This benefits both U.S. employers seeking highly skilled workers and foreign professionals seeking legitimate employment opportunities. Historically, the level of scrutiny has varied based on factors such as prevailing economic conditions and policy changes. Greater emphasis on verifying credentials often correlates with periods of heightened concern regarding immigration or program integrity.
