This is a cool story but I'm really confused by the details. Like he seems to fly around and do pieces of this at a time, but then there's the weird bit of him walking 3000 miles in the US to get to the embassy, though that wasn't part of his 'walk'?
Also next time don't skip Africa xD
I also got confused by the timeline of him getting deported from Russia. I think he's allowed to fly out as long as he returns and continues the journey on foot. You can see on the world map of the journey he makes steady progress from 1998-2006 but then he doesn't finish crossing Siberia until 2017.
