Overall smooth procedure, as it is explained.
One thing for immigrant visa, don't stress over arriving too early. You will be waiting in same line as non-immigrant visa. But one make sure you do get appointment number before you even pass the security for immigrant visa. It's possible they forget to give you, since most of the people in line would be for non-immigrant visas.
Whatever number you would get, chances are odd numbers will be called by window 1, even numbers would be called by window 2. Don't stress too much if even numbers are going too fast or odd numbers are going super fast.
You will have finger prints taken there.
Once you are cleared from there and submitted the documents, you would have to wait, until you are called from Window 7. That's where you take some oath.
