This study investigates the writing revision strategies used by 16 Saudi English as foreign language (EFL) students. Two research methods were employed. First, think-aloud reporting was used to gain insight into the thought processes utilized by the students, and to study the revision strategies that Saudi male university students make use of while writing compositions in L1 Arabic and L2 English. Second, a semi-structured interview was conducted with the aim of supporting the think-aloud data. Analysis of the think-aloud sessions and the interviews revealed that most of the time, strategies were used more frequently when students wrote in English rather than when they wrote in Arabic. In addition, it was found that in general, specific strategies used when writing in Arabic were also used when writing and vice versa.
