You can acquire your visa at the Yerevan airport. In this case, please do so before proceeding to immigration control. You will see the visa desk as soon you get off the escalator in the airport arrivals hall. The 21-days visa fee is 3,000 AMD = USD8. Please have this amount in cash as the Yerevan airport’s ATMs not always serve the cards issued by foreign banks.
Alternatively, you can obtain an e-Visa through the Ministry of Foreign Affairs of the Republic of Armenia. An e-Visa is equivalent to a conventional visa, but no paper is inserted in your passport and there is no need for you to contact an Armenian diplomatic mission to submit an application. Applications for e-Visas can be submitted online, verified on line. E-visas will be approved and issued to you via email within two business days. (Note: Typically short-term university visitors apply for a 21-day e-visa under category 7 or regular tourist category 1 without any problems.) A 21-day visa costs $8 on line. Please apply for your e-Visa at least seven days prior to your departure (http://www.mfa.am/eVisa).
