If a person has already filed the I-485 application when the dates were current, but then the Visa Bulletin date retrogresses to a date before the priority date, the foreign national would still accrue the benefit of being able to remain in the U.S. with renewable EAD or work authorization and permission to travel, even after completing the six years on H1B status in the U.S. However, the I-485 could not be approved until the date again becomes "current."
