What is an alien?
An alien is “any person not a citizen or national of the United States.” This definition comes from Section 1101(a)(3) of the Immigration and Nationality Act of 1952 (with amendments by Congress through 2001). Contrary to Marxist diversity-speak, the word alien is not “hate speech.” It is defined by United States statute. Aliens can be either legally or illegally in the U.S.
In Constitutional Law, or more specifically Immigration Law, an alien is anyone who is not a national or citizen of the United States. Any number of individuals living or staying within the borders of the United States can be considered aliens. All aliens are non-citizens, but a national is neither a citizen, nor an alien. The basis for categorizing individuals as aliens is set by the Immigration and Nationality Act of 1952 (INA). The INA defines the different categories to which an individual alien is assigned as follows; resident and non-resident aliens, immigrant and non-immigrant aliens, and documented or undocumented/illegal aliens. In more general terms, United States federal immigration laws define whether or not an individual is an alien. Federal immigration law also elaborates the legal rights, duties, and obligations of an alien living within the United States, as well as how and whether an alien may pursue naturalization. Naturalization refers to gaining naturalized citizens
Aliens aren’t the stuff of science fiction, but science fact. An “alien” is any species that is found out of its historically normal range. In the vast majority of cases, the species will not survive because it is not adapted to its new locale (it is estimated that only 10% of introductions survive). For example, its new habitat may have slightly different temperatures, seasonal variation, humidity, wind, predators, pests or diseases. However, in a minority of cases, a plant will be able to survive in its new location. Even more rarely (perhaps in 10% of cases), an alien will thrive in its new location better than in its original location. This is often because of the absence of a predator or pest that would normally keep the species in check, and because of a biological trait that predisposes it to fast colonisation, such as a fast growth rate and the production of many seeds. When this happens the species can spread quickly to become very common and dominant in its new habitat, and i
