My approved I140 priority date is Oct 2021 and I am still with the petitioning employer. Lets assume my priority date becomes current after 10 years, then next 10 years I should be able to do H1B extensions or transfers with any employer and unlimited time right?
Do every employer need to file perm and I140 or I can ask the last employer ‘closed to my priority date becomes current’ to file perm and I140, port my current I140 date and then file I485 when ultimately priority date becomes current?
