Hi Rocio0010, no offense taken at all. The members of VisaJourney have been an exceedingly helpful resource for me and I am grateful. I lucked out and obtained my wife's CR-1 within 6 weeks through the U.S. Consulate in Ho Chi Minh City during the pandemic, and the green card within 6 weeks of arriving in the U.S..
The confusion on my part was searching for I-797 and finding a lot of references stating the I-797 form is a notice of approval which I've learned it is clearly not.
So, is your spouse carrying an expired green card with a 24 month extension? We had to return my wife's I-551 (via the I-90 form) to fix her name order.
