Exactly what my son has to do. He spent 4 years living in Amsterdam while attending University there. He was blind sided about the documentation needed for this job.Security clearance investigations require verifiable addresses, employment, schooling, activities, references, etc with no gaps for a period of time. If you were out of the country for an extended period the investigators need some way of verifying with the host nation that you are being truthful about your whereabouts and activities.
