teaching english in Moscow

I would think that someone "licensed" (whatever that is supposed to mean) in English language, wouldn't make such basic grammar mistakes.

thanks for your remark !  would I haven written in an academic style?    there was just a mere question.... thank you anyhow

Grammar, spelling and general ability to use the English language isn't normally an issue here as many members aren't native speakers and a lot are still learning the language.
Comments regarding poor English skills are usually unwelcome, but they are valid when someone claims expert status, as in this case as you're asking about teaching the language.
The standard you're displaying here is likely to put potential employers off as your many errors suggest you'd be pretty crud at the job.

but u can make the difference between a native and non-native one:)

Being a native speaker of a language doesn't mean you're any good at it.
Your English needs a lot of working on before you have any hope of teaching.
You might be okay in a small school with low expectations, but that's as far as it goes. Students with higher level skills will rip you to bits.
