Expatriate management faces many challenges. The role has become more complex as companies send more employees abroad but expect greater support and services. Expatriate managers must address a wide range of issues from tax to culture while facing pressures to cut costs from the business units they support and expatriates themselves. Specific issues include the perception that expatriate HR is not effective, balancing the many areas of focus required, and a shortage of experienced staff with in-depth knowledge of the field.
