What is the difference between an EB3 and an I-140 petition?

Answer 1

Starting on August 28, USCIS will begin accepting Premium Processing requests for petitions involving one of two employment-based immigration categories within the employment-based “preference.” Those categories involve EB-3 Professionals, (i.e. immigrant workers with bachelor degrees who are members of the professions), and EB-3 Skilled Workers, (i.e. immigrant workers capable of performing skilled labor requiring at least two years of education, training or experience). Employers file for both categories using an Immigrant Petition for Alien Worker (Form I-140). Premium Processing is not available to “other workers” in the EB-3 category for jobs that do not require two years of education, training or experience.
In addition, USCIS has revised and will release a new Request for Premium Processing Services form (Form I-907), to include expansion of Premium Processing Service to the newly designated classifications. Any Premium Processing Service requests for Form I-129 received BEFORE August 28, 2006 must use the current Form I-907 with the revision date of 04/01/2006. USCIS will not accept any Premium Processing Service requests for Form I-140 before August 28, 2006
