This tour does not include the cost of your visa.
Most nationalities can enter Kurdistan without a visa, including US, Canada, Australia, and EU passport holders.
For other nationalities, you will need an e-visa to enter Kurdistan. Contact the nearest KRG representative to you and find out how to apply for one. Here is a list of KRG representatives around the world.
You just need to mail them copies of your passport and application form along with some cash. You will receive your e-visa by email within a week.
Be sure to print out the e-visa and show it at the ‘VISA’ booth upon arrival at the airport. You can then stay up to 30 days in Kurdistan, but you won’t be able to travel to other parts of Iraq beyond the Kurdistan region. Note that a visa for Arab Iraq is very hard to get and costs around US$500.
