The most reliable way to verify sponsorship history is by checking the U.S. Department of Labor’s Office of Foreign Labor Certification (OFLC) database. You can search the Labor Condition Application (LCA) disclosure data to see if a specific company has filed H-1B petitions in previous years. Additionally, third-party platforms like H1BGrader or MyVisaJobs aggregate this public data to provide user-friendly insights into a company’s sponsorship volume and approval rates.

No, not all US tech companies sponsor H-1B visas. Sponsorship is a voluntary and costly process that involves legal fees and strict compliance requirements. While large tech firms (often referred to as 'Big Tech') frequently sponsor visas due to their need for specialized global talent, many startups or smaller firms may lack the resources or the legal infrastructure to handle the H-1B petition process. Always confirm a company's sponsorship policy during the initial screening or interview phase.

Look for phrases such as 'visa sponsorship available,' 'must be authorized to work in the US,' or 'H-1B sponsorship provided.' If a job description explicitly states that they 'cannot provide sponsorship' or 'requires US citizenship/Green Card holder,' it is a clear indicator that the company will not sponsor an H-1B visa. If the description is silent on the matter, it is best to ask the recruiter directly during your first contact to avoid wasting time on roles that do not offer visa support.
