Is there a chance they will ask me to prove English fluency?

There is no formal, standardized requirement to prove English fluency for the O-1. The review centers on your extraordinary ability in your field, not on your language level.

Immigration officers typically focus their evaluation on your achievements and the evidence that demonstrates your expertise. A language proficiency test is not part of that focus.

That said, having a strong command of English helps in practice: it makes interviews easier, simplifies handling documents and official procedures, and supports your ability to work independently in the United States. In some contexts, communicating well can reinforce that you are able to carry out your activities and integrate into the local professional environment.

Since every case is unique, it is worth confirming up-to-date guidance from official sources such as USCIS and, if needed, consulting a specialist rather than relying on services that promise guaranteed outcomes.
