"When in Rome, do as the Romans" - Expatriates may feel like a fish out of water in a different country. They are bound to adapt to the social and cultural differences they face in a foreign land. From food to traditions, everything differs. Why! Even the electricity volts differ.
This issue is mostly faced by female expatriates. There are some countries where females are not given an equal status as men, and also certain kind of clothes are not tolerated in many places. Some countries have a high crime rate too. Female expatriates have to certainly take care of these considerations.
Finding a house can be a big challenge for an expatriate. Getting a place which is decent enough to live in, and also something which is affordable, can be wearisome. Another problem is that, many locals are reluctant in renting or selling their property to expatriates, because they do not fully trust them.
