The answer is "yes and (sometimes) no". If you are not a native speaker of English, you must prove your English proficiency. You may do this by sending to us your score from one of the internationally recognized English testing systems, IELTS being one of them, but not the only one.

In exceptional cases, you may avoid submitting to us English testing results, if you manage to convince us that your command of English is sufficient: for instance, you lived and/or worked several years in English-spoken environment, studied in university with English as the teaching language, etc. But we do not promise to accept every explanation of this kind.

We prefer the IELTS test, but TOEFL, Cambridge Certificate of Proficiency in English are acceptable as well. If your working language should be other than English, it is up to you to provide the proof of sufficient proficiency in this language.
