Barriers to students traveling abroad are minimal.
Safety is the major concern.
Difficulties surface when students traveling abroad do not anticipate how to handle situations prior to departing. Students must have high energy levels as well as be able to carry their own luggage up and down stairs and on and off trains, which can be very tiresome, particularly after a night on a train. Problems in relationships at home, illnesses, accidents, financial difficulties are relatively minor but do happen. Prior planning can avert these difficulties when abroad for most students. Language is rarely a barrier in most European countries, as many Europeans like to practice speaking English.
