I served as a volunteer reviewer at 10 conferences. Does this count as 10 pieces of evidence?

Serving as a reviewer at conferences can count as evidence for the EB-1 visa, but each piece of evidence requires robust documentation and individual evaluation by USCIS.

When it comes to EB-1 visas, it is important to understand that USCIS (United States Citizenship and Immigration Services) evaluates each piece of evidence individually, within the set of proofs demonstrating extraordinary ability in your field. The EB-1 category requires the applicant to present robust and high-quality evidence proving relevant and recognized contributions in their area of expertise.

In your case, serving as a volunteer reviewer at 10 conferences can indeed count as important contributions. However, each of these ‘pieces of evidence’ must be presented with documentation that clearly demonstrates the relevance and notoriety of the conferences, as well as the impact and significance of your work as a reviewer.

USCIS examines whether these activities were recognized and served as an indicator of your exceptional ability. Thus, even if they are 10 distinct events, the recognition and relevance of each will be individually evaluated, and not necessarily cumulatively as ’10 pieces of evidence’ that automatically strengthen your case.

Furthermore, it is crucial to keep in mind that the quality of the evidence is as important as the quantity. Therefore, it is recommended that all documentation – invitation letters, event descriptions, certificates, or any other proof – be organized in a way that highlights the impact of your work in the field. This approach strengthens your case before immigration authorities.

Finally, we emphasize the importance of complying with US immigration laws and seeking information directly from official sources or qualified specialists when preparing your documentation. Beware of marketing campaigns or offers that promise quick results. Building a solid case requires time, organization, and careful verification of each piece of evidence presented.
