Globalization has cause organizations between nations to be more integrated and interdependent than before. Taiwan, being an economy based on international trade, has abundant experience in international assignments among business organizations. Due to the changing environments, organizations developed various forms of international assignments. Other than the standard expatriate assignments, short-term assignments, international business travelers (IBT), commuter assignments, rotational assignments and virtual assignments are emerging alternatives to deal with international issues. The IBT is likely to be a big portion of international assignment used in Taiwan, as the number of business travel rises. A qualitative research was held and 11 IBTs from Taiwanese firms was interviewed. The findings are as follow: 1. The proportion of time spent overseas per year differs from IBTs with different backgrounds. 2. The positive factors of IBT work are increase of specialties training, increase of job satisfaction and the rise of personal development. 3. The negative factors of IBT work are pressing work schedules, culture and cognition gaps, time differences and abnormal work schedules, health and safety concerns, separation of family and friends and confliction between work and personal schedules. 4. The standard of travel class influences IBTs¡¦ perspective towards the job and also their life style. 5. IBT cannot totally be substituted.
