As mentioned above, USCIS officers are disinclined to wade through lots of pages of support materials. It is advisable to provide a concise outline of the artist or group’s history, emphasizing particular achievements (i.e. awards or honors, performances at particularly notable venues, etc.) and providing quotes from articles contained within the support materials. If support materials contain testimonials, these should be specific, listing particular accomplishments and descriptive information. For any articles, USCIS advises that petitions provide detailed information about the publication such as circulation, a clear identification of the name of the publication, and for any online-only sources, any available information about web traffic numbers would be helpful.
