Hi, I wanted to ask a question about my potential status as a native Russian speaker. I was born in Moscow but migrated to England and then the US when I was eight. I've completely mastered English, although I do have a slight accent (I'd be very surprised if a non-native speaker could pick up on it), but I'm worried that I might be at a disadvantage because I'd imagine that language schools would prefer a bona fide American/Brit. In your experience/opinion, given a TEFL certificate, a BA in Linguistics, possibly a bit of teaching experience, and a giant network of extended family members in high places, would I have a fighting chance at getting a half-year winter-to-summer contract at a good language school in Moscow or, preferably, St. Peters burg? Thanks in advance.

No there is no problem at all. Infact in my views you should be proud of your citizenship.

There won't be any problem like that for you and you seemed to be well educated and lack of confidence is what I see in you.

Being a Russian is not your problem but as Prita said Its pure lack of confidence.
