This study was a cross-sectional investigation into the request strategies used by Iranian learners of English as a Foreign Language and Australian native speakers of English. The sample involved 96 BA and MA Persian students and 10 native speakers of English. A Discourse Completion Test (DCT) was used to generate data related to the request strategies used by each group. Selection of request situations in DCT was based on two social factors of relative power and social distance. Although results revealed pragmatic development, particularly in the movement from direct to conventionally indirect strategies on the part of EFL learners, learners with higher proficiency displayed overuse of indirect type of requesting; whereas the native group was characterized by the more balanced use of this strategy. The lower proficiency learners, on the other hand, overused the most direct strategy type. In terms of the influence of the social variables, the findings of this research revealed that as far as social power is concerned EFL learners display closer performance to native speakers. But considering social distance, it seems that Iranian EFL learners have not acquired sufficient sociopragmatic knowledge to display proper social behavior.
