The EB-2 NIW (National Interest Waiver) is a category that, among other criteria, requires consistent proof of investment in activities and research that benefit the national interest of the United States. For this, it is essential to present a series of documents that demonstrate, in a detailed and organized way, that the resources were effectively applied to relevant research.

In general, the main documents that can help prove investments in research are:
1. Financing Documents and Contracts – proof of research grants, grant contracts, or funding agreements entered into with recognized institutions that evidence financial investment in research projects.
2. Technical Reports and Scientific Publications – progress reports, published articles, and conference presentations that illustrate concrete results and impact of the work performed.
3. Letters of Recommendation and Expert Statements – detailed testimonials from researchers that reinforce the relevance and advances provided by the investments.
4. Accounting Records and Proof of Disbursement – bank statements and payment receipts related to research expenses.
5. Supplementary Documents – patents, awards, and agreements with institutions that strengthen the evidence of the investment’s impact.

It is emphasized the importance of strictly following the U.S. immigration laws and seeking specialized guidance, as the clear and consistent organization of the documentation is decisive for the process analysis and to demonstrate alignment with the country’s public interest.
