can I change job from next day after getting approved i140?

[mike123]

My i140 approved and I want to change my job.
should I have to stay with my employer for 180 days so, employer can not revoke it.

you can change the job as soon as you have approved i140. you can retain your priority date when you file it again.

Under the law effective from 17 January 2017, employee can retain the priority date once an I-140 is approved. even if a day later the employer asks for a revocation. There is no requirement that the employee be employed with that employer for a certain period of time.
