Carl Shusterman: From your deion it seems that you are entitled to the earlier priority date. Of course, this depends on a number of factors, including whether both labor certifications were filed for the same occupation, whether the new company was a "successor in interest" to the old company, etc.
Question #12: If I go to another employer and file another RIR, I-140, do I get to keep the original 8/97 PD?
Carl Shusterman: The rule is this: Whenever you have a visa petition approved under EB-1, EB-2, or EB-3, and for whatever reason you do not use that visa petition but file a new one instead you are entitled to the earlier priority date as long as the second petition is also under EB-1, EB-2, or EB-3. Remember, however, that it is the approval of the petition, not merely of the labor certification, that allows you to establish and keep the earlier priority date.
