What are some obstacles that might cause one to consider moving to a new country?

Some obstacles, also known as push factors, could be politics, cultural factors, social, or environmental factors. For politics, you might be a refugee. For cultural factors, you might be a part of a minority religion. For social, you might be female in a male dominated area. For environmental, you might have an environmental disaster and need to leave.
