For an O-1A visa, USCIS specifies that an alien with extraordinary abilities in the sciences, education, business, or athletics may apply. Extraordinary abilities in arts (acting, dancing, painting…) are required for an O-1B visa. The definition may be interpreted in a broad sense, therefore what really matters is how the supporting material and the argumentation are prepared to convince the USCIS officers of the alien outstanding achievements and impactful presence in the United States.
