Immigration is the movement of people from one country to another for the purpose of settling there. Every country has its own set of laws to determine who is allowed to immigrate to their country and under what circumstances they can enter. People from nearly every country move to other countries every year – over 190 million in 2005.
The reasons to leave the country of one's birth are
varied and include political instability, few job opportunities, lack
of social ties, or natural disaster. Countries that receive a large
number of immigrants can face difficulty integrating new arrivals into
the culture, legal system, education system and economy. In many
countries around the world, immigration is a hotly debated topic.
Objections that residents have from the receiving company include fear
that new immigrants will take jobs away, burden healthcare and
education systems, or fundamentally change the culture. Many countries
welcome immigrants, though, as they bring needed skills and fresh
entrepreneurial spirit. Another challenge for every country is illegal
immigration. Governments are unable to manage the levels of strain on
the system if they do not know who is actually in their country.
