I got my I140 approved in Jan 2019 with the current employer. In mid of 2019, due to the acquisition employer name got changed. They filed the I140 amendment and which got approved in Dec 2019. I am looking for a job change now. Do I need to serve 180 days again after my recent I140 approval (dec2019) before changing my job or I am good to switch based on the first I140 approval. Please help me. Thank you.
