Today in class we read a packet on migration, immigration, and emigration. migration is when someone ones moves from one place to another like when Mexican come to the U.S. Immigration is entering a country, so if I were to enter in Canada that would be immigration. Emigration is moving from one country and entering and living permanently to another country. Another thing I learned I the packet is that unauthorized immigration is when a person enter a country without going through any paper work or seeking for asylum, which means they're basically not allowed. Undocumented means they don't follow the rules governing the U.S. An illegal alien is when they're not a citizen.
