<human>:  What are the differences between immigration and emigration?
<bot>: The main difference between immigration and emigration is that immigration is the process of people entering a foreign country to live permanently, while emigration is the process of leaving one’s home country to move to another country permanently. Immigration often involves applying for legal status in the new country, whereas emigration does not. Immigration is a process that adds new members to a population, whereas emigration is a process that reduces its total number.
