I've been in the US for over 90 days now and have not received my green card. I received my SSN after 2 weeks of being in the US. I spoke to USCIS this morning and they are advising me that i have to attend a biometrics appointment which was scheduled for me a week ago. Is this normal for CR1 visas to attend a biometrics appointment? Should i be worried? All my biometrics were taken in Sydney Australia and my fingerprints were taken at my immigrant visa interview.
