The EB-2 NIW visa is a category widely used by professionals who have a distinguished trajectory in their fields, whether in terms of advanced academic training or significant contributions to their professional area. In this context, many wonder if it is essential to prove participation in scientific events to strengthen the petition.

In practice, there is no specific legal requirement that demands proof of participation in scientific events, such as conferences, symposiums, or congresses. However, this experience can be a relevant element to demonstrate your active involvement in the scientific community and to evidence the quality and importance of your work – attributes that can reinforce the argument of national interest.

It is important to remember that each case is analyzed uniquely, where various types of evidence – such as publications, citations, mentions in awards, letters of recommendation from specialists, or other indicators of excellence – can be presented. Furthermore, it is worth noting that the discussion about the relevance of attending scientific events may vary according to the applicant’s field and profile.

For this reason, it is advisable to always seek updated information and guidance from reliable sources, respecting the United States immigration laws. Beware of miraculous promises or marketing campaigns that guarantee results, as it is fundamental to correctly inform yourself and seek out professionals or consulting firms with credibility in the subject.

In summary, although proof of participation in scientific events is not mandatory, it can be an important piece in a robust set of evidence that demonstrates your qualification and the positive impact of your work in the United States. Always be attentive to current rules and seek information from secure sources to make the best decisions in your process.
