If a labor certification, I-140 or employment-based adjustment application has been filed for more than 365 days, prior to the expiration of his current period of H-1B status, petitioner can request further extensions. Even though the labor certification or I-140 was not filed before 365 days of expiration of the 6-year term but if an I-140 is approved, the worker may still get the extension either for one year or three years depending on certain circumstances. The I-140 does not have to be from the same employer.
