This paper surveys studies that explore the experiences of multilingual English teachers (MET) teaching English to learners from the Eastern part of Asia (China, Japan, Korea, and Thailand). By MET, I refer to teachers who speak English as one of their multilingual repertoires and teach English to students from different linguistic backgrounds than their own (Galloway 2014). Studies have recently shown that Outer Circle has been establishing a role in providing English education to Expanding Circle learners. Moreover, it is also becoming common for teachers from Expanding Circle to cross national borders in order to teach English in another Expanding Circle country. This paper reviews studies specifically addressing those teachers and identifies three contact zones: (a) study abroad programs in Asian Outer Circle; (b) EFL classrooms; and (c) digital space. As there are some distinctive characteristics pertaining to different contact zones, I first briefly review the previous studies by each zone, followed by a synthesis of the research findings with a focus on how environment influences teachers' experiences based on the lens of intersectionality and situated power dynamics. Then, I conclude the review by discussing the problematic nature of treating this unique teacher population as pseudo-native speakers from a pedagogical perspective.
