Is i140 withdrawal limit 180 days calendar days or actual working days?

Hi Anil,

if i want to keep my i140 and lock the priority date should I work with the current employer for 180 days? Is this 180 days is calender days. or actual working days?

Eventhough my current employer withdraw the i140 once I move to another employer.
Thanks

You should work with with your current employer who sponsored your i140 for at-least 180 calendar days to be on safe side.

You can port your priority date easily with no issues if i140 is not revoked for 'fraud or misrepresentation".
