Are you interested in the question of how to become an ambassador to one of the states? Well, the answer is not at all difficult.
In order to take this post, you will first need knowledge of foreign languages. Which ones? It depends on which country you wish to travel to. But in any case, knowledge of the English language, as well as a number of others, if possible, will not hurt you. In particular, Arabic, French and others are quite common in the world.
Do not forget that you will have to communicate both in your native language and in the language of a foreign country, and your knowledge of languages should not let you down in any of the cases. As a linguist, you must speak Russian competently. No less competently you should be able to use foreign languages, there can be no question of any accent. After all, this can be taken as an insult, and besides, poor knowledge of a foreign language, or poor command of it, make communication difficult. All this can cause mutual misunderstanding of people, and, consequently, of entire states. Therefore, the ambassador's foreign language must be perfect.
What else can be useful to you if you decide to become an ambassador? Education, of course. And the highest. MGIMO is desirable, although there are other educational institutions of a similar level, whose graduates have every chance of getting this post. But still, even the best specialist will not get this post right away. In order to get it, a person will have to work hard and prove himself well. Most likely, at first he will have to work as an attaché, eventually rising to the rank of consul. Then he can become a secretary, and then, if he can prove himself well, an ambassador.
The main thing for an ambassador is a good reputation. Without one, a person will not be able to get such a position for one simple reason. The ambassador is the face of the state, and this person must represent his country, and only in the best light. And only a person whose reputation is not tarnished can do this. So honor and conscience are no less important for an ambassador than education and knowledge of languages.
All this together gives a person a chance to get this high position. Of course, such a career is easier for someone - if there are high-ranking acquaintances or relatives. You can try to take advantage of this opportunity, making your way to the top of your career - try to make useful contacts and support them. After all, this is also diplomacy, and extra practice will not hurt you.
