A government-approved guide must escort US citizens at all times. Independent travel in Iran for Americans has been banned due to the closure of Iranian foreign missions in the US. The same applies to Canadian and British citizens. All Iran authorization code applications must be accompanied by a detailed resume for U.S., Canadian, and British passport holders. This document must list the passenger’s education and career history – comparable to what you would prepare for a job application. Due to strengthened security standards, the passenger's father's name, job history, and social accounts are also demanded.
