This paper seeks to find out the degree of the rhetorical variation between the introduction sections of research papers published in English for international journals and those published in Farsi in the area of computer sciences. To this end, a corpus of 100 Farsi and 100 English research papers were collected and analyzed sentence by sentence based on Swales’ 1990 CARS model. The results revealed that the introduction sections of Farsi research papers in this field differ those written in English in terms of Move 3 which introduces briefly the research: this move was less observed in Farsi papers compared with the English ones. However, some degree of convergence was found, mostly in the frequency of occurrence of Move 1 the general dimensions of the area of study is presented. The same was found also to be true about Move 2 by which the readership is sought to be convinced that there is enough justification for the study to be carried out. The study generally concluded that there was a significant difference between the frequency of moves and steps applied in the introduction parts of English and Farsi research papers in the area of computer sciences.
