My wife was approved CR1 immigrant visa through consular processing and she is entered the USA on May 22nd, 2021. As soon she got her visa stamp from the US Embassy in Colombo on May 20th 2021, we paid the immigrant fee to USCIS. It has been 75 days since we paid the immigrant fee and she still hasn't received the physical green card by mail. I have few questions to get clarification on:
1. When you pay the immigrant fee, do you get assigned a new USCIS case number (different to the USCIS case number assigned when you applied for I-130 petition)?
[When I check the case status against the USCIS case number assigned for the I-130 petition, it says the case was sent to Department of State. Also it displays that the case is closed. However if I check the case status against the USCIS case number given in the receipt when we paid the immigrant fee, it says they have received the payment. Which case number should I need to refer to check the case status of the physical green card production and delivery? ]
2. How long does it take to receive the physical green card by mail ?
[Some forums says 90 days and some says 120 days - what is correct?]
Thank you!
