I read about this a few months ago and realized our passport would expire a couple months after our January 18 trip. We did the app, got the pics, and sent it in. We had our new passports in about 2 weeks. Just get a new one so you don't have to worry about it. We got our old passports back in the mail a few days later. My wife had to send her birth certificate with the old passport because we realized a few years ago that it said she was a man on her passport which no one ever brought up to or from Jamaica 3 times or Bermuda.
