What is mass deportation, and is it a practical solution to illegal immigration?

Mass deportation is where a country deports a whole bunch of people out of their countries who may be considered an illegal to their country.

Explanation:

For example, Trump deported a whole bunch of people back to Mexico. This question that you asked can vary as an answer but i think it isn't the most practical immigration because it leaves thousands of people without a home and in poverty.

good luck
