I need some information on Immigration in the 20th Century.
And also include an article or just send the link for it.
Immigration in the 20th century has evolved over time. There were bans of individuals who were lacking in education, those of poor health and also disease carriers in earlier times. Some rules applied till the 90's and also into the 21st century with imposed mandatory detention and deportation taking place because of various cited reasons. See details at http://en.wikipedia.org/wiki/History_of_laws_concerning_immigration_and_naturalization_in_the_United_States#20th_century.
