Visa appointment schedule for the Holidays

I just read that the last appointment for the year is December 20, with the visa pick up on Friday the 21st. After that embassy appointments will not be until January 2. So if we don't get an appointment by the 20th???? then we won't be going until the beginning of January. There is a slight possibility that we may make it by the 20th. If we do, we owe a BIG thank you to Debbie and "the lady" at the lab who has expedited Dillon's DNA sample. Keep your fingers crossed.
