What to do
Check the expiry date of your passport, and make sure it is valid.
Apply for a visa in time before your travel date to Islamic Republic of Iran. Follow the Iranian laws and regulations regarding visa conditions.
Keep your official documents, such as ID, passports, airplane tickets and valuables in a safe place. Keep a photocopy or scanned copy of your passport and ID number to be used as a reference at the embassy in case of losing your passport.
Save the contacts of the embassy of the state of Qatar in Tehran to use it when necessary.
In case you have any problems please contact the Qatari embassy in Tehran as soon as possible and inform the officials about your problem.
In case you are interrogated regarding any issue, inform the mission immediately.
In case of lost or stolen passports, inform the regional police station for a police report. Remember to keep the report to apply for a "pass ticket" from the Qatari Consulate and to apply for a replacement passport when you return to the Qatar.
What not to do
Do not give your passport to anyone claiming that he is from the police or security services before checking his credentials.
Do not leave children alone in big events, markets and shopping malls.
