I am a GC holder and submitted the I-130 application for my wife 37 days ago. I haven't received any response or receipt notice mailed to me from the USCIS till date. I also attached form G-145 with the application to receive electric notifications via Email / Phone number, but haven't received any notifications on it as well.
Here is the timeline:
Mar 22, 2019 - Mailed Application to the USCIS
Mar 23, 2019 - Application received by the USCIS
Mar 27, 2019 - Check cashed by the USCIS
Doesn't anyone know how long do they take to mail back the receipt notice by mail or respond via email / phone for the receipt number.
Since I do not have the receipt number, I can't even check the case status online. What should i do?
Thanks in advance.
