Omanis visiting this country are eligible for visa-on-arrival

Muscat: Omanis who hold an "ordinary passport" will be able to obtain an Armenian visa on arrival, the Sultanate’s Embassy in Moscow announced.
This comes after the Armenian officials released a list of countries where citizens can receive a visa-on-arrival.
In a statement online, the Embassy said, "We would like to draw attention to the decision of the official authorities of the Republic of Armenia that only Omani citizens that hold ordinary passports can obtain the visa upon arrival at the Zvartnos International Airport in Yerevan."
Other countries where citizens can obtain an Armenian visa-on-arrival include Albania, Bahrain, China, India, Kuwait, and Turkey.
Different countries have a variety of passport types. But, the "common passport" is the one that is issued to a regular citizen.
