Armenian Embassy Visa
British and EU passports will no longer require a visa in order to visit Armenia.
The entry stamp will only be valid for the first 90 days of entry to the country, Children arriving on a British passport with parents entering Armenia on an Armenian passport will require an Armenian passport to leave the country; this is stated in Armenian law.
Your passport should be valid one for at least a period of six months from the date of entry into Armenia.
If you are a dual national entering Armenia using your Armenian passport and you are travelling with children coming in with a United Kingdom passport you need to be aware that under the Armenian Law a child of an Armenian passport holder is automatically regarded as Armenian no matter what and must present an Armenian passport to leave the country.
The child actually may be even be detained on departure if he/she can’t produce one.
