Student mobility across national borders has been increasing at an extraordinary pace. Correspondingly, much research has been conducted into issues concerning learners that move internationally to pursue learning in a culturally different country. To a great extent, vigorous debate and research did promote cross-cultural diversity, understanding and communication. However, few studies have looked into international Chinese students' use of laughter in much detail, given that laughter plays a significant part in shaping or molding meaning. This article demonstrates with examples of a group of ICSs on how their use of laughter alters the meaning of utterance in speech. The findings offer insights that aim at promoting cross-cultural understanding and communication so that a much smoother and a more inclusive and successful adjustment of these learners can be facilitated.
