Yes. For the O-1, business clients can provide recommendation letters, and they can be useful for demonstrating your market recognition. What makes a difference is the quality of the letter, not just who signs it.
To carry weight in your case, these letters tend to work best when they:
- Are detailed and include an objective assessment of your performance.
- Describe how your work benefited the company or contributed to relevant projects.
- Concretely demonstrate the impact and recognition of your work in the field.
Even so, client letters should not be the only evidence. A strong petition package combines varied sources, including letters from independent experts who offer an impartial evaluation, as well as articles, awards, and other forms of public recognition. This diversity reinforces the overall credibility of your case.
Since each profile is evaluated individually, it is worth confirming updated requirements and structuring your evidence with specialized support before filing.
