Language Center International is a private language school established in 1987. From 1987 to early 1989, its classes were only tutorial in nature, and there were no regularly scheduled group classes. In March 1989, the school was incorporated under the name of Language Center International, and group classes were held on a regular basis in Detroit, Michigan. In 1992, LCI moved to larger facilities in Southfield, Michigan and in 2015, LCI moved once again to a larger facility, also in Southfield. Its facilities now include several instructional classrooms, a computer lab, a tutoring room, an instructors' office, and administrative offices.

LCI teaches English as a Second Language (ESL). Up to eight levels of instruction from beginning to advanced are possible in morning, afternoon, and evening classes. All classes emphasize active student participation and strong teacher-student interaction. Six terms per year are offered. Seven-week terms are: January-February, March-April, September-October, and November-December. Six-week terms are given spring and summer: May-June and June-July. Tutorials for ESL and foreign languages are scheduled when requested.

All LCI instructors must have a minimum of an undergraduate university degree in a field related to language instruction. Many instructors either have advanced degrees or have completed graduate courses. Almost all instructors and staff have lived, worked, or studied outside the United States and know at least one foreign language.

LCI has been authorized under federal law to enroll non-immigrant aliens since 1990. It is accredited by ACCET (Accrediting Council for Continuing Education and Training), which is recognized by the United States Department of Education.
