What is an extension letter (of an expired green card)?

[Grail An 1]

I want to have a test in DMV for a learner's permit. I have an expired green card but i have the sticker at the back of the card which states it's extension for a year. The dmv didnt accept it because they were looking for an extension letter. WHAT IS AN EXTENSION LETTER? The uscis didnt give me any letter when i files for my renewal, they just put the extension sticker at the back of my green card. So please can someone tell me what an extension letter is and where can i get it?

Usually it's an i797 form saying you are approved. They're basically looking for a new expiry date.

Maybe they need a legal document I'm not sure. Maybe the person at the desk has never dealt with this situation before.

Good luck
