There are more than just two categories of citizen and/or immigrant in a country. There are a total of four basic categories.

1.) Citizen - A baby born to a citizen of a nation becomes a citizen of that same nation by default. A Swedish baby born in Sweden to citizens of Sweden is Swedish and entitled to all the benefits Sweden offers to its citizens.

2.) Legal Immigrant - A person who is a citizen of another nation and desires to immigrate and become a citizen of another nation. This person fills out the proper paperwork, pays the proper fees, learns the language and wants to assimilate and become a supportive citizen of that new nation. They respect the local laws and the natives of the new nation.

3.) Illegal Immigrant - A person who is a citizen of another nation and desires to immigrate and become a citizen of another nation. This person doesn't fill out the proper paperwork, doesn't pay the proper fees but wants to learn the language and assimilate. This person wants to become a supportive part of that new nation but instead skirts laws and sneaks across the border to get in for various reasons.

4.) Invader - A person who is a citizen of another nation and desires to immigrate and become a citizen of another nation. This person has no desire to fill out the proper paperwork, doesn't pay the proper fees and refuses to learn the local language or assimilate. They could care less about the ways and customs of the new nation and only want free social benefits. They will take over entire neighborhoods, only practicing their customs and attempt to breed the natives out by having many children. They also harbor ill-will towards the natives and will even assault, rob, rape and even murder the natives.
