I reached out to my local HR team last week (big international company with 90k+ employees worldwide, HQ in Europe) to let them know that I have received the extension letter. Today, they said they went on the USCIS website and checked, and that they do not need the letter. No re-verification needed according to them. I told my HR rep that it would make me feel a lot better if they could add a copy to my file. HR rep said they would check again and circle back. For literally every job I applied for, there was a question in the process regarding whether or not I am legally authorized to work in the US. If an auditor comes in, what evidence would my employer still have that I am actually authorized to work here if they did not add the letter to my file?! I am just trying to not get fired What is everyone else's experience with that?
