There are two ways to obtain a visa to Iran. You can apply at the nearest Embassy of Iran or get an Iranian visa at one of Iran’s international airports (visa on arrival). Either way, you require a pre-approval called e-visa and this is a guarantee for the issue of your tourist visa.
All the formalities aside, just contact me at Email: firstname.lastname@example.org or via WhatsApp +98 936 917 3113 and get your e-visa within 3 days! Do not worry about the sanctions, you can transfer the fee to my European bank account.
