I entered the US on December 19, and paid the immigrant fee on December 20. However, the USCIS case tracker on their website suggests that the receipt number, which I received in an email upon the payment, is invalid. Does anyone have the same issue, and what's the solution? Haven't yet received my SSN either.
Another issue is that my visa was CR1 but I entered after 2 years of marriage. Yet, the officer at the airport wrote "CR1" on the stamp. Are they going to send me a 2-year or 10-year green card in this case?
