Let’s start by explaining a bit about the EB-2 NIW visa. This type of visa is intended for professionals who have advanced qualifications or exceptional abilities and can demonstrate that their work is relevant to the national interest of the United States. In the case of researchers in the health field, the focus is on proving that their contributions can generate significant benefits for the country, and not necessarily on the geographical origin or internationality of their experience.

Regarding the proof of international experience, there is no strict requirement that the researcher has worked outside their country of origin. What the United States Immigration Department really values is the quality and impact of their work – whether it is developed nationally or internationally. Evidence such as publications in specialized journals, mentions in prominent projects, recommendation letters from experts in the field, and the adoption of their research by other professionals can demonstrate the relevance and influence of their contributions, regardless of where they were carried out.

Even though international experience can strengthen the case, it is not mandatory. What matters is to present a robust portfolio that proves the excellence and relevance of your research in the health field. Every element that evidences your ability to contribute significantly to the interest of the United States can make a difference.

In this regard, it is essential that all documents are organized and that the information presented complies with the requirements of U.S. immigration laws. We remind you that strictly following immigration laws is essential. We always recommend seeking specialized advice to guide you on the process details and avoid falling for scams or miraculous promises of guaranteed results. Being well informed and having trustworthy professionals can help build a solid process aligned with the requirements of the immigration authorities.
