If the previous university degree was completed in English it is not necessary to submit a further proof of your English language skills. Otherwise a certificate of TOEFL iBT with a minimum score of 85 points or an IELTS score of at least 5.0 must be provided. Your command of English during your telephone interview will also be taken into account. For German applicants (and „Bildungsinländer” – international students who completed their secondary education or a university degree in German) the High School Diploma might be accepted if it certifies sufficient English language skills.
