Re: remembering everywhere you visited
If you are abroad and traveling between other countries, and there are no visas or stamps in your passport, I wouldn't worry too much. For example, let's say you flew to Paris, then took a train to Amsterdam, a train to Munich, then another train to Vienna and then you flew back to the US from Vienna. So there's not really a record of your travel between the countries, since no one stamps passports anymore if you're not arriving into an airport. You will have to remember that you traveled to France and Austria, but the land-based stuff in between not so much. I forgot to put Spain on my daughter's GE renewal (we flew into UK and left from Spain), and that didn't even matter. She got her new card a week later.
I'm on Day 80 "Pending Review"
expiry 11/19
husband & daughter both got GE within 2 weeks/no interview
