My wife applied and sent out her AOS packet (application for greencard, work permit and travel docs) back in May, and as of today she checked her status online and it says Case closed. Does this mean that her travel docs wasn't approved? We are nervous as we tried to take our time to make sure we filled out everything correctly before mailing. Once we received the notice, it was instructions and location for her biometrics appointment, which she did attend and do, so I'm not sure why she's getting this message. Here's a screenshot of what it says.
