How can I stay in the U.S. with an AOS EAD but I-94 expiring?

When did you file the I-485? What date was the EAD approved?

You are in an authorized period of stay while I-485 is pending. You need to wait for AP to arrive before you may travel to avoid abandoning your pending I-485 application. Generally, a new employer may port you after I-140 is approved and your I-485 has been pending for 6 months or more and if the new job offer is in the same or similar occupation as the original PERM.

Once your I-140 is approved and your AOS has been pending for 180 days or more, the new company may file the I-485 supp J. to port you to their company and sponsor you for the green card. The new offer must be in the same or similar occupation as that on the original labor certification with the old company.

I assume you have a pending I-526 and, since you are physically in the United States, you are eligible to file AOS, Forms I-485, I-765, I-131, which you have done. You received EAD (category 09) based on the I-765 filed with AOS. You have not yet received approval on your I-131 application. Therefore, you are currently in a status created by the Attorney General. An administrative status for those who have applied and from whom USCIS has received the filing fees. The I-485 receipt is the document that shows you are in the status created by the Attorney General. You do not need to leave the U.S. If you choose to travel abroad, wait for the I-131 approval. The processing of I-131 may take 17 or more months. Renew your EAD. work authorization 120 days prior to the expiration date on your current card.

The rules are not complicated, but there seems to be confusion. Your immigration attorney should be able to answer your question here, but I will attempt to provide some clarity. Do not travel abroad before your Advance Parole I-131 application for travel is approved. Once that happens, you can safely travel. Meanwhile, once you have filed your AOS document, you should have no issues until you receive a decision as long as you have a valid passport. You can also work with an approved EAD.
