I waited 3 weeks before approval

I didn’t hear anything back for 3 weeks so I contacted my local congressman to inquire about it on my behalf and they told me it was approved on March 13th. I also check this with a live chat agent and they confirmed that our case is under expedited processing but I still haven’t received anything from USCIS directly to me. the live agent told me this is pretty normal. I think you should hear from them within 30 business days but you can always inquire about it through Emma (from the live chat agent)

Hi @I K, How can I question Emma about my case ?
