LUGI: Hope all goes smoothly. Thankfully you will only have to go through "the process" once...but as it was pointed out...it is a time consuming process...so make sure you have plenty of time in Atlanta between flights.
BTW, (off topic) we look forward to visitng your "neck of the woods" one day. Oldest son (now a freshman in college) took 4 years of German in high school and has 3 German classes in college under his belt. He loves the lanuage....and all I can say is "field trip"!!!
