Student Voices
-
Student A (China) ISI is a large, historical, and experienced company, so I felt it was reassuring.
-
Student B (Canada) I visited the school before enrolling. The building is new and very clean, and the school is a great environment to study in.
-
Student C (USA) I didn't want to go to a school where everyone spoke English, nor did I want to go to a school where no one spoke English at all. It's the perfect balance - not too isolating, but not enough English speakers so that you get stuck in your comfort zone.
-
Student D (Mongolia) ISI has courses that specialize in job hunting, and I thought that it might help me build my career in Japan.
ISI offers a curriculum and support system that meets the needs of each and every international student.
