Iran is to issue visas for all foreign nationals upon their arrival at Iranian airports, except for those from Britain, the US and seven other countries. Visas in those cases must still be applied for in their home countries.
The move is aimed at promoting tourism with the numbers of foreign visiters having recently increased by over 12 percent .
The boost in tourists appears to have been triggered by the signing of a nuclear deal between Tehran and the Group 5+ (Russia, China, the US, Britain, France and Germany) which came into force in January.
The seven other countries are thought to include Pakistan Canada Somalia Bangladesh Iraq Jordon Afghanistan but the list is yet to be confirmed.
