Are you applying for EB-1 visa classification under the “extraordinary ability” category? Do you have any previously published material about you in any publication? Are you confused about what does publish material means and what will come under such criteria?
One of the simplest methods to determine if someone has gained recognition in their field due to their extraordinary abilities is to examine whether their work is considered noteworthy by the media.
It is clear that the USCIS seeks published material that focuses on the alien’s extraordinary ability, whether describing their skills or their work.
USCIS will not be interested in any evidence of published material if that is totally not related to the alien’s extraordinary ability.
