So our application was approved on July 25th! I thought that meant we're near the end of the process. However, there's still probably about 6 more months to go, according to other peoples' experiences. We'll get sent a package of forms to fill out and paperwork to prepare for more evidence. After we submit them and they're approved we get an interview date. Then if that goes well they apply for a green card and it gets sent here. So that brings our estimated timeline to February 2015 before we can move back.
Oh well... at least the first big step is over and went well. On to gather plane tickets, receipts, call logs, and pictures!
