They mailed my bottom portion back to me stamped with the date received. I think it took about a week and a half or soHow long does it USUALLY take to get a confirmation email/letter back from HR that they received your ERR. I put mine in last weekend and called HR last Monday. She said she did receive it and was going to email me a confirmation email, but I haven’t gotten it yet. Just trying to make sure it doesn’t fall through the cracks for this NCEPT.
