Why do migrants face challenges? notes

Transportation, improvements that have promoted globalization, such as motor vehicles and airplanes, have diminished the importance of environmental features as intervening obstacles. Most of the major obstacles that immigrants faced were political. The U.N. classifies countries into four types of immigration policies; 1) maintain the current level of immigration, 2) increase the level, 3) reduce the level, 4) no policy. Similarly, emigration policies are identified by the same four classes. Twenty-one countries seek more immigrants, thirty-two want fewer immigrants, one hundred sixteen wish to maintain the current level, and twenty-five do not have a policy. Ten of the twenty-one countries are in Europe including most of the Communist countries of Central and Eastern Europe. The thirty-two countries with with policies to reduce immigration include ten in Southwest Asia & North Africa as well as eight in Sub-Saharan Africa. Of course these aren't all my notes, but that would take like until past 12pm so this is where I'm going to stop.
