International business people who are sent abroad on temporary assignments face psychological challenges similar to sojourners. They must successfully interact with local counterparts to achieve work goals while adjusting to an unfamiliar culture. Expatriate effectiveness directly impacts international commerce, so selecting candidates with interpersonal and cross-cultural skills is important. However, cultural differences can negatively impact work practices, leadership styles, and group performance for expatriates working in foreign environments. Proper support, preparation, and consideration of cultural distance are keys to expatriate adjustment and success overseas.
