Will there be any chance to revoke or cancel approved i140 if we file 2nd i140 with same employer . My employer is willing to give approved labor which is better (EB2 ,PD-2003) than my labor (EB3, PD-2003) . But right now i am on 6th year . I got a 3 years H1B extension recently. If my first i140 canceled (??) how about my H1B . is it still valid?
