The present study attempted to investigate any changes in a group of Korean undergraduate EFL students' perceptions on L2-L2 communication. Email exchanges with two different EFL groups were carried out. Chinese and Turkish EFL students were recruited for a Freshmen English course at a university located in South Korea. The students' initial, as well as post-study, perspectives on L2-L2 email exchanges, students' email messages, and their paragraph writing samples were collected for analysis. The major findings of the present study were the positive changes in the participants' perspectives on L2-L2 communication and their awareness of the need for more authentic L2-L2 communication opportunities in L2 learning. Also, L2-L2 email exchanges coupled with contextualized grammar lessons using participants' own email messages were particularly found useful, and the analysis of two selected participants’ paragraph samples showed improvement in their L2 writing. Suggestions for future research were also provided.
