Immigration versus migration, what is the difference and what can it do? The difference is very simple, the one is going in and the other is going out. So migration means from one place to another place. While immigration is people coming into a country.
The nomads were the founders of this. And now people who travel from one country to another and people who want to start their lives over there.
These people are very important to a country as they will bring something new which is beneficial for everyone. The reason why it has so much negativity is because people has this in their nature. And also when there is too much from something. Too many people coming to your country is negative, the same as too many people leaving from a country.
