First of all the moment, your I-140 is approved no matter which category EB-1 or EB-2, the Priority Date is yours to keep that means if you got your green card filed in let's say 2017 and you left this employer after the I-140 approval, they revoked your I-140 and you started another green card in 2020 your Priority Date will be still 2017 because your I-140 was approved. So the moment the I-140 was approved the Priority Date becomes your property and it can be carried across categories, across employers, and across geographical areas. So if you go from a PERM filing in New York to an employer in California and your previous filing was EB-3 next filing is EB2 or even EB-1 you can carry the date of the work petition as long as the I-140 was approved. The moment the I-140 is approved, the Priority Date is yours.
There are limited exceptions unless the I-140 is revoked for fraud, etc., by the USCIS. Even if the employer revokes the I-140 you will keep your Priority Date. In addition to that, if the I-140 gets approved and stays approved for 180 days you will not only carry your Priority Date you will carry your right to extend your H-1 through any employer indefinitely. You will get a second benefit after 180 days and if the lawyer revokes the I-140 you will still get the benefit of both Priority Date and the right to extend your H-1 through any employer. The government has also said if you have an H-4 EAD for your spouse, your I-40 stayed approved for 180 days your wife's or your husband's H-4 EAD is safe even if the old employer revokes the I-140 later on as long as the I-140 stayed approved for 180 days. So if you left but the I-140 stayed approved for 180 days H-4 EAD is safe. That, in a nutshell, is the general law. More

Thanks a lot for all your efforts in helping me get to this stage in my immigration journey. Me and my spouse received our green cards last weekend. The journey started back in 2006. I have had a totally professional experience with Rajiv's team. Hope I did not miss anyone who has helped me in this journey. I would like to sincerely thank Pramita, Vani, Mathew, Rita, Bharathi and above all Rajiv for all your efforts. My special thanks to Prerna Mehta for answering all my queries patiently for the last 4 years.
