I am sorry to ask this question but even after going through the AC21 details I do not understand if I should apply for an I140 after changing to a new empoloyer. I know for sure that we have to send a letter of employment, a detail of the job being performed and the salary from the new employer. I sthis enough or do I have to still apply for a new I140.
Thanks to all who respond
