Seven Reasons eh?

1) Language difficulties. Malapropisms, also some jerk could have told her that some foul words mean "hello". Just an aside "never" ask Chinese students to teach you their language ;-)

2) Cultural differences.

3) Coming from a different country, makes any female student in the "I wanna tap that!" category.

4) Co-ed toilets, and change rooms (hey it's worth a shot, or two).

5) Blitzes some subjects.

6) She's actually part of the old KGB.

7) She can drink the guys under the table, so any attempts to get her drunk will
fail ... badly.

Political activist

There doesn't seem to be too much activity on this. The basic setup is interesting. So I'll give my shot here:

The Russian could be politically active and she had to leave Russia, because she has been giving too loud arguments of the Putin and friends. Concrete pressure from government agencies. And now when she gets into trouble because there are Russian spy/spies also in the class. So some direct and not so direct trouble making and some constant surveillance of the things she is doing. You can imagine things like when you open your curtain in the morning somebody is watching you and stuff .. anyway I expect more of this to be dialog related than any action movie, but I haven't clear idea of what kind of movie this will be.

This is not seven reasons, but rest of the stuff can be collected from other shots.

Seven Reasons a Russian Exchange Student is a Problem "in the car pool".

1) She was educated in Russia.
2) She is completely backwards in the way she sees the world.
3) She is always right.
4) She was raised by an Alcoholic father and a mother who looked the other way.
5) She has never been told "no" only that she's better than those in the West.
6) Only the good looking girls in Russia get to ride in cars--she now thinks she's very attractive since she's in the car.
7) Her hair is died blonde but she doesn't admit it when called out on it.

Embedded

The Russian girl should be an embedded journalist working on a 'doc'
or a pilot for a cross country show for MTV or something 'punky'...

better than a classroom - could be a 'field trip' - a cross country trip in a car...

And beyond all of Bob's suggestions, she should always sound correct -
even if her grammar is a bit more complex than traditional English...

This might prove an interesting wrinkle to Jani's suggestion...

Perhaps if she sounds imperial, (ie. super sanitized) the writer won't *only* have to rely on imperialist humor...

From Russia with love

The first and the most obvious thing that came into mind was of course, that the chick is way too hot to handle: the make up, the push ups, a lot of skin, a skirt that some would call a belt, and high heals that break bones if you fall from that high. The guys cannot concentrate on the education from drooling at her and the girls can't stop envying her. Nothing is working because she is there.

...now that I got that out of my system, let's think of something deeper.

Maybe she could be a scam artist looking for a proper victim. She has just arrived from Moscow with her boyfriend who has some russian mafia connections. They are accompanied by a couple of mafia thugs. The setting for the movie is a Finnish language course that the exchange students are attending. The Russians think that they can find some fresh, gullible people to do some task that somehow will gain them a substantial amount of money that they cannot access directly.

Sounds like drama/action. Maybe someone could come up with a comedy plot.

Russian nationalism

How about a character who's a rapid Russian nationalist? Someone wishing for the supposed glory and power of the USSR.

You could play on the different understandings of Russia today. For example, Gorbachev is viewed in the West as a benevolent character who helped dismantle the monster that was the Soviet Union. But for many in Russia, he is "the man who destroyed our country!!" (quote from a young Russian politician).

That could give you the 'conflict' you need in a script.
