How many citations is needed to get the EB-1 Green Card
This depends on which EB-1 Green Card category is being applied for and what other criteria an applicant satisfies, but the more citations, the better for the Extraordinary Ability and the Outstanding Researcher or Professor categories.
In general, an EB-1 Green Card applicant (with the exception of those in the Multinational Executives and Managers category) should have at least 100 citations to make their case; however, 200-300 citations would be best for this competitive process.
