Bushby planned to walk around the world but he and Kieffer, who was accompanying him on this leg of the journey, were detained on April 1 when they entered Russia from Alaska across the Bering Strait.
A court in the Far Eastern region of Chukotka ordered the two to be deported from the country and to pay a 2,000 ruble fine (about $70).
The decision would also mean the two would be banned from visiting Russia for five years.
