This study identified the degree of interest in learning English among Vietnamese learners learning English in Korea. The survey data was based on the questionnaire on foreign language self-learning strategies and consisted of a total of 20 items to meet the communicative language teaching method. The SPSS 26.0 program was conducted to identify the total distribution, the difference in average between groups, the significance between genders, and the difference by learning period. The results show that students are generally more interested in reading and writing than in listening and speaking. In addition, there is a significant difference in the learning period rather than the difference between genders. The results of this study need to be used as reference materials for foreign learners learning liberal arts English at Korean universities.
