I sent my documents to the Chicago offices, it is almost a month and we have not received any confirmation that they recived. I called the USPS and they told me that the package was delivered. What should I do?, I'm worried about my information.

Hello, USCIS prefer that you use THE website, you will have to register. Or From the USCIS website, click on my case, will need Alien or a notice number.. I hope this helps. 🤘

It happened to me too, I was able to talk to a representative 2 or 3 weeks ago, she said have to wait 60 days, if still don't hear or receive the notice of action then I can call back, but now I'm trying to call , can't get hold of them. It's frustrating 😒
