President Rouhani issued a decree to facilitate foreign tourist arrivals in Iran.
According to the decree, the visa-stamping waivers are extended to all the airports of Iran. The passports of foreigner visitors are not physically stamped.
We hope that the decision improves the amount of the tourists who visit Iran. This policy makes visiting Iran more easy than before.
In 2018, the government of the United States announced that those who have visited specific countries such as Iran may face restrictions to enter the realm of the United States.
If one wants to know if this policy may work, well, should wait and see.
