Number of Americans working in Russia

[Stephen J. Frank]

Hello!

        I will be giving a talk to high school students of Russian about
how they can use the language in their future work. I would like to tell
them the number of Americans currently working in Russia. Does anyone know
the number and source and/or can tell me where to find the information?

        Thanks.
