Many professionals who come to AEI are already working or looking to work in a US business environment. These workplaces operate in English, and communicating effectively at a managerial and professional level requires more than basic fluency — it takes advanced listening, writing, and speaking skills. AEI offers Business English Enrichment Online, a 16-hour self-paced course, to help our students build those skills on their own schedule.This is online course designed specifically for advanced non-native speakers.
