To begin with, a lot of people believe they can earn higher incomes by working overseas. As a result, living standards and economic conditions for their families will improve, especially for people who migrate to developed countries from third world countries. There are, by comparison, other negative aspects that people should remember. The family members have a chance of a cultural shock, because there could be certain rituals and practices that do not suit them. To overcome this problem, families should learn common language about the land to which they are going. It will minimize the "cultural shock" and help avoid unpleasant accidents. Family members should also have an idea about the country's laws and rules prior to travel. This should avoid law-related issues. Photography of government buildings or monuments, for example, is a criminal offence in some countries.
