USCIS has resumed premium processing option for form I-140, in limited circumstances, since June 29, 2009. Premium Processing is filed on form I-907 and requires a fee of $1,000.00 that the employer pays which will require USCIS to issue a decision or request for evidence within 15 business days of the form I-140 submission.
Premium processing is available under the following circumstances:
*EB-3 professionals, EB-3 skilled workers and EB-3 other workers;
*EB-2 Members of professions with advanced degrees, EB-2 exceptional ability; and
*EB-1 aliens with extraordinary ability, EB-1 outstanding professors and researchers
Premium processing is still not available for EB-2 exceptional ability or members of professions with advanced degrees seeking national interest waivers or EB-1 multinational executive or manager. For more information please refer to
