This exploratory study examined the potential connections between informal digital learning of English (IDLE), strategic competence for cross-cultural communication and perception of varieties of English. A total of 266 Korean EFL university students, who had no overseas experience, filled in a questionnaire survey. Follow-up semi-structured interviews were also carried out to complement the quantitative data. Results of structural equation modelling showed that perception of varieties of English mediated the relationship between IDLE and strategic competence for cross-cultural communication. The qualitative data also confirmed that EFL students without overseas experience tended to adopt more effective cross-cultural communication strategies when their perception of different varieties of English became more positive through their engagement in IDLE activities. These results can offer pedagogical insights into how ELT researchers and teachers can better prepare contemporary English learners for cross-cultural interactions in multicultural environments, whether in digital or face-to-face milieus.
