Do not be afraid of the state of repair in the building. But there are kind and helpful people working inside who are ready to advise and help with the translation of documents and forms for those who do not speak Armenian.
Everything is not as scary as in the reviews. On the contrary, even. I really liked the friendly staff. You can fill out an application in Russian.
There are no queues (you need to sign up electronically for a month somewhere, but this is no longer a question for the branch).
