We also got a letter from USCIS (U.S. Citizenship and Immigration Services) regarding our I-600A. We have been approved and our application has been forwarded to the National Visa Center! It shouldn't be long before we have our I-171H....the final piece of the paperwork puzzle!
It has taken us soooo long to do our paperwork. It will feel great when everything is sent in and we can be put on the waiting list.
