Just an idea, what do you think. Are there teachers of Russian to expat children. Have you seen the demand of parents wanting their children in good Russian schools. These schools don't realise the the adabtability of these children to learn another language in another school whilst living in a country which is not their first language. These kids are fantastic in picking up another language, especially if they are living in that particular country.

Perhaps you can help them to get into these Russian schools, instaed of their second choice of putting them into into International schools. Assist them with blending with Russians, it will do them good.

Why not isus this further in the teacher's folder.
