follow-to-join in home country
I used the follow-to-join procedure in the home country and I have the interview on jan.20. I started the procedure in sept'04. A friend of mine did the same and he got his daughter in US in 3 months.
We just sent the documents over to the US Embassy (copy of I551 stamp, I140 approval, birth certificate, marriage certificate) and they had us come for the interview with the originals and forms I230, I134, and I864.
