While English is embraced worldwide as a global means of communication, its teaching and learning is a contested arena of contacts between the so-called English native-speaker culture and local learner cultures. In this study, we investigate Iranian university students' viewpoints on the necessity and justifications for learning English and their awareness of international policies of promoting this language. A group of 855 male and female students of different fields of study at six major universities of Tehran responded to a researcher-made questionnaire and 28 participants were interviewed for more in-depth explanations about their standpoints. The findings indicate that the participants are in absolute favour of learning the English language as an undeniable necessity as a multifaceted communicative instrument. Moreover, they seem to have limited sensitivity to the potential sociopolitical functioning of English and the policies and plans for promoting the teaching and learning of this language around the world.
