I got scheduled for the interview yesterday. Hopefully it doesn’t get canceled again.

I did go to the field office on March 6th. I checked in on the 2nd floor as was mentioned in the notice. They of course could not find the appointment so I spoke to the supervisor and he said he could not find the appointment either. He said he was going to put my application back in line for scheduling an interview. It’s been close to 3 weeks and there has been no change yet. I was reading in the Facebook groups that filing an FOIA request can sometimes help expedite the interview date so I did that on March 8th. I’ve only gotten an acknowledgment from USCIS that they’ve received my FOIA request and will let me know when the documents are ready. 

Right, but the green card is expired. The website doesn’t mention anything about an extension notice. As somebody who’s been denied boarding at the gate because of the green card plus extension notice combo, I’ve become extra careful with all requirements(not traveling to Jamaica, but Mexico)

Yes do not travel to Mexico with an expired Gc and extension letter. Get a visa instead. 
 
Canada explicitly states that they allow expired gc+ permanent resident cards plus valid passport as valid entry documents. Not sure why United was giving you problems with that. 

I was traveling to Cancun from Chicago in July 2022 with United. I got my boarding pass at the check in counter. When I got to the gate, they told me that upon secondary verification, they decided that my documents were not sufficient for entry into Mexico and they had taken me off the flight and my bags were being sent back to the carousel. No matter what I showed them, they refused to let me board. 
 

I was in the Dominican Republic last month. I also have an Indian passport and expired permanent resident card and extension notice. Had no problems going and coming. I had emailed the Embassy and had printed out their response confirming that I did not need a visa in case the airlines gave any problems. 
 
Mexico on the other hand does not accept extension notices(the airlines here will not let you board with an extension notice) and I had emailed the embassy in Chicago and they wanted me to get a tourist visa. 

Yes, that is normal. The stamp in the passport serves as your green card now.

I filed my i751 at the end of July 2021. Received 18 month extension shortly after. Looks like a 24 month extension notice is in the mail today. Service center is Lincoln, Nebraska.

I went to the chicago west facility in the first week of September. My i797 said my conditional resident status was extended 18 months past the expiration date on the green card, but the staff knew that those letters were now being extended to 24 months so they gave me a drivers license with an expiration date of 2 years from the expiration date on my green card. I was in and out within 30 minutes with a temporary paper license and my Real ID compliant license came in the mail about 10 days later.

There’s a lot of good advice here, but I think you need an immigration lawyer to help you. You are already 6 months late in filing your i751 and face the real risk of having your conditional permanent resident status terminated.
