It is important to understand that, for the O visa, it is not exactly about submitting a fixed number of pieces of evidence, but rather presenting a robust set of evidence that proves your recognition and achievements in your field of expertise.

Usually, for those who do not have a single highly relevant award (such as an Oscar or a Nobel Prize, for example), it is necessary to demonstrate that you meet at least three of the criteria established by the United States Citizenship and Immigration Services. Each of these criteria requires its own evidence, and the quality of the evidence is more important than the mere quantity.

For example, if you choose to show your high-level involvement in your field, your testimonials and important publications can be combined to meet one criterion.

In summary, before submitting any documentation, it is ideal to carefully review which criteria you best fit and prepare as much consistent, objective, and verifiable evidence as possible for each one. It is essential to always follow United States immigration laws and prepare carefully for the process. Seek reliable information, avoiding companies and marketing promises that guarantee results, as each case is unique and must be treated with attention and seriousness. Remember that the consistency and credibility of your documents are the key to a well-founded petition.
