I600A to Korea!

We just received a letter from the State Department's National Visa Center and it says that our petition and approved I600A application will be forwarded to the US Embassy in Seoul, Korea where eventually our daughter's adoption interview will take place for her to receive her VISA! It was even signed by the Bureau of Consular Affairs! It all sounds so official! Even though we haven't even been matched with our daughter yet, the paperwork is there waiting! One more step completed!
