What we tend to do when we're approaching countries to get travel documents is that we go with lists of people. It's not done on a case-by-case basis—it might be, it depends on the circumstances—but generally we would go with a list of people that we have in order to see if we can find the appropriate documentation for people on that list.
That's one of the data problems, unfortunately, that doesn't sync back necessarily with the case management system, but we're going to do a better job at matching those efforts.
Over the last couple of years, we have documented over 300 interactions with foreign governments to try to get them to give us the documents we need.
