-If they want to file a new PERM, they may open another PERM position for you and use the new prevail wage from DOL for this new position to meet the salary they can afford to you. It should be easy to open a new position with new prevail wage. You can use the priority date of the old I-140 for the new I-140.
我如果换公司可能保留已经批准的PERM和I140吗?
-No. You only can use the priority date for your new I-140 from another employer.
