Answer:
“Alien” is the term used to refer to all those individuals who move or establish themselves in lands other than those of birth.
The alien can reach the status of “resident” when he has already crossed the time limit of stay in the country to obtain residence; they are also required to have a visa. This is often considered one of the main steps to achieve citizenship. However, this entails certain responsibilities, since, if one of the rules that are imposed to achieve the statute is not fulfilled, the procedure will be started again, after a specific period of time.
