The EB-2 NIW visa requires you to present strong evidence of your professional achievements and the positive impact of your work in the United States. A fundamental part of this evidence package is the recommendation letter, which aims to confirm your accomplishments and demonstrate recognition of your expertise by relevant professionals in your field.

Regarding the question about using only letters from graduate school colleagues, it is important to highlight that although these documents can add value to your case, they are generally not sufficient on their own. Immigration authorities tend to give more weight to letters from experts who have no direct ties or personal interests with the applicant, such as letters from renowned researchers, project leaders, or professionals who have worked with your activities independently.

Thus, combining letters from colleagues with recommendations from other professionals who can offer an unbiased perspective on your contribution to the field can significantly strengthen your case.

Additionally, it is essential that all evidence be submitted in accordance with U.S. immigration criteria and laws. Therefore, we always recommend caution and consulting reliable sources or specialized companies, thereby avoiding exposure to inaccurate information or guarantees of results made by unregulated marketing campaigns.

In summary, while letters from graduate school colleagues can be part of the set of documents intended to demonstrate your professional merit, the ideal is to have a variety of recommendations that include independent expert opinions, enriching the assessment of your background and contributions in the professional domain.
