Can international collaborators’ letters be included in an EB-2 NIW petition?

Yes. Letters from international collaborators can be part of an EB-2 NIW petition and often add real value, because they show that recognition of your work is not limited to one country. They reinforce the idea that respected professionals, both inside and outside the United States, see merit and impact in what you do.

To truly contribute, a letter of this kind needs to go beyond generic praise. The strongest ones tend to include:

• The concrete relationship between the letter writer and your work, making clear why that person has the authority to evaluate it.
• Specific examples of the impact and originality of your contribution, rather than vague statements.
• The context of your relevance in the global community of your field, connecting that role to the benefit for the United States.

Each letter works best as part of a cohesive set, alongside the other evidence in the file, not as a standalone piece. Authenticity is essential: evaluation is done on a case-by-case basis, and claims that the documents do not support will weaken the petition.

No letter guarantees approval. To confirm how this type of evidence fits your profile and review updated guidance, consult the official USCIS source or an immigration specialist.
