The difference between American immigration prison and prison

In fact, the American immigration prison is not a prison. Sitting in an immigration prison does not put you in prison, which limits the freedom of immigrants before being named to some extent. Regarding immigration supervision, there are two corresponding situations: one refers to the time that a person must live in the immigration country in order to retain his immigration status. The other refers to the time you have to live in an immigrant country in order to become a citizen of that country. The above two kinds of immigration supervision are very inconvenient for friends whose life focus is still at home. Every time they enter or leave the country, they must carefully calculate the time. If they make a mistake, they may lose their immigration status.
