An immigrant is defined by the Merriam-Webster dictionary as "a person who comes to a country to take up permanent residence".
An immigrant is defined in 8 U.S.C. § 1101 : US Code - Section 1101 as:
(15) The term "immigrant" means every alien except an alien who is within one of the following classes of nonimmigrant aliens... (F)(i) an alien having a residence in a foreign country which he has no intention of abandoning, who is a bona fide student qualified to pursue a full course of study and who seeks to enter the United States temporarily and solely for the purpose of pursuing such a course of study... as "any person not a citizen or national of the United States". The term is defined by United States statute, in Section 1101(a)(3) of the Immigration and Nationality Act of 1952 (with amendments by Congress through 2001). Aliens can be either legally or illegally present in the U.S.
Thus, an immigrant is an invited guest - a person who comes to a country where they are not a citizen in order to settle there. The term "immigrant" implies permanent, legal, residency. (Although because of amnesties and status adjustments, about 25% of currently legal immigrants first came to the U.S. illegally).
An alien is defined in 8 U.S.C. § 1101 : US Code - Section 1101 as "any person not a citizen or national of the United States. 8 U.S. Code § 1325 - Improper entry by alien states:
(a) Improper time or place; avoidance of examination or inspection; misrepresentation and concealment of facts
Any alien who (1) enters or attempts to enter the United States at any time or place other than as designated by immigration officers, or (2) eludes examination or inspection by immigration officers, or (3) attempts to enter or obtains entry to the United States by a willfully false or misleading representation or the willful concealment of a material fact, shall, for the first commission of any such offense, be fined under title 18 or imprisoned not more than 6 months, or both, and, for a subsequent commission of any such offense, be fined under title 18, or imprisoned not more than 2 years, or both.
(b) Improper time or place; civil penalties
Any alien who is apprehended while entering (or attempting to enter) the United States at a time or place other than as designated by immigration officers shall be subject to a civil penalty of—
(1) at least $50 and not more than $250 for each such entry (or attempted entry); or
(2) twice the amount specified in paragraph (1) in the case of an alien who has been previously subject to a civil penalty under this subsection.
Civil penalties under this subsection are in addition to, and not in lieu of, any criminal or other civil penalties that may be imposed.
The term alien was used in United States law just after our country was founded. The Alien and Sedition Acts of 1798 consisted of four bills enacted into law. The Naturalization Act made it more difficult for an immigrant to become a citizen. The Alien Friends Act allowed the president to imprison and deport dangerous non-citizens. The Sedition Act allowed the president to imprison and deport dangerous non-citizens who were from a hostile nation. It also criminalized making false statements that were critical of the federal government.
An illegal alien is defined in the Department of Homeland Security Media Resources Glossary as "A foreign national who (a) entered the United States without inspection or with fraudulent documentation or (b) who, after entering legally as a non-immigrant, violated status and remained in the United States without authority."
Thus, an illegal alien is "a foreigner who has entered or resides in a country unlawfully or without the country's authorization." An illegal alien is an alien - that is, a foreign national - who has illegally entered the United States, or who enters legally and then deliberately overstays their visa. An illegal alien is a criminal subject to as much as six months in jail for first offense and subject to federal felony charges for subsequent entries after initial deportation. (From What is an alien?, Juan Mann's Frequently Asked Questions About Immigration and the Law, VDare.com, 11 December 2002.)
The term illegal alien was coined by a Federal Appeals Court in 1950.
Colorado defines an illegal alien as "anyone who has entered the United States illegally and is deportable, or anyone who has 'overstayed a visa' or otherwise violated the terms of his or her legal admission into the United States. Sometimes known as an 'illegal immigrant.'" (From Implementation of Senate Bill 06-090 Performance Audit, Colorado State Auditor, Department of Public Safety, Department of Local Affairs, May 2009.)
Laws, Regulations, and Guides Immigration and Nationality Act, summary by the U.S. Citizenship and Naturalization Services:
The Immigration and Nationality Act, or INA, was created in 1952. Before the INA, a variety of statutes governed immigration law but were not organized in one location. The McCarran-Walter bill of 1952, Public Law No. 82-414, collected and codified many existing provisions and reorganized the structure of immigration law. The Act has been amended many times over the years, but is still the basic body of immigration law.
The INA is divided into titles, chapters, and sections. Although it stands alone as a body of law, the Act is also contained in the United States Code (U.S.C.). The code is a collection of all the laws of the United States. It is arranged in fifty subject titles by general alphabetic order. Title 8 of the U.S. Code is but one of the fifty titles and deals with "Aliens and Nationality". When browsing the INA or other statutes you will often see reference to the U.S. Code citation. For example, Section 208 of the INA deals with asylum, and is also contained in 8 U.S.C. 1158. Although it is correct to refer to a specific section by either its INA citation or its U.S. code, the INA citation is more commonly used.
Title 8, Code of Federal Regulations, summary by the U.S. Citizenship and Naturalization Services:
The general provisions of laws enacted by Congress are interpreted and implemented by regulations issued by various agencies. These regulations apply the law to daily situations. After regulations are published in the Federal Register, they are collected and published in the Code of Federal Regulations, commonly referred to as the CFR. The CFR is arranged by subject title and generally parallels the structure of the United States Code. Thus, Title 8 of the CFR deals with "Aliens and Nationality", as does Title 8 of the U.S. Code.

Legalized Aliens, U.S. Citizenship and Naturalization Services, Glossary of Terms, 10 April 20166:
Certain illegal aliens who were eligible to apply for temporary resident status under the legalization provision of the Immigration Reform and Control Act of 1986. To be eligible, aliens must have continuously resided in the United States in an unlawful status since January 1, 1982, not be excludable, and have entered the United States either 1) illegally before January 1, 1982, or 2) as temporary visitors before January 1, 1982, with their authorized stay expiring before that date or with the Government’s knowledge of their unlawful status before that date. Legalization consists of two stages--temporary and then permanent residency. In order to adjust to permanent status aliens must have had continuous residence in the United States, be admissible as an immigrant, and demonstrate at least a minimal understanding and knowledge of the English language and U.S. history and government.
Permanent Resident Alien, U.S. Citizenship and Naturalization Services, Glossary of Terms, 10 April 2016:
An alien admitted to the United States as a lawful permanent resident. Permanent residents are also commonly referred to as immigrants; however, the Immigration and Nationality Act (INA) broadly defines an immigrant as any alien in the United States, except one legally admitted under specific nonimmigrant categories (INA section 101(a)(15)). An illegal alien who entered the United States without inspection, for example, would be strictly defined as an immigrant under the INA but is not a permanent resident alien. Lawful permanent residents are legally accorded the privilege of residing permanently in the United States. They may be issued immigrant visas by the Department of State overseas or adjusted to permanent resident status by U.S. Citizenship and Immigration Services in the United States.
Resident Alien, U.S. Citizenship and Naturalization Services, Glossary of Terms, 10 April 2016:
Applies to non-U.S. citizens currently residing in the United States. The term is applied in three different manners; please see Permanent Resident, Conditional Resident, and Returning Resident
The formal removal of an alien from the United States when the alien has been found removable for violating the immigration laws. Deportation is ordered by an immigration judge without any punishment being imposed or contemplated. Prior to April 1997 deportation and exclusion were separate removal procedures. The Illegal Immigration Reform and Immigrant Responsibility Act of 1996 consolidated these procedures. After April 1, 1997, aliens in and admitted to the United States may be subject to removal based on deportability. Now called Removal, this function is managed by U.S. Immigration and Customs Enforcement.

On November 9, 2015, the 5th U.S. Circuit Court of Appeals in New Orleans ruled against Obama's immigration plan. Read the ruling here. The ruling contains approximately 39 references to the term illegal alien. Footnote 14 on pages 4-5 explains the terminology:
14. Although “[a]s a general rule, it is not a crime for a removable alien to remain present in the United States,” it is a civil offense. Arizona v. United States, 132 S. Ct. 2492, 2505 (2012); see 8 U.S.C. §§ 1182(a)(9)(B)(i), 1227(a)(1)(A)–(B). This opinion therefore refers to such persons as “illegal aliens”:
The usual and preferable term in [American English] is illegal alien. The other forms have arisen as needless euphemisms, and should be avoided as near-gobbledygook. The problem with undocumented is that it is intended to mean, by those who use it in this phrase, “not having the requisite documents to enter or stay in a country legally.” But the word strongly suggests “unaccounted for” to those unfamiliar with this quasi-legal jargon, and it may therefore obscure the meaning.
More than one writer has argued in favor of undocumented alien . . . [to] avoid[] the implication that one’s unauthorized presence in the United States is a crime . . . . Moreover, it is wrong to equate illegality with criminality, since many illegal acts are not criminal. Illegal alien is not an opprobrious epithet: it describes one present in a country in violation of the immigration laws (hence “illegal”).

Ct. 2492, 2497 (2012)). “[I]legal alien has going for it both history and well-documented, generally accepted use.” Matthew Salzwedel, The Lawyer’s Struggle to Write, 16 SCRIBES JOURNAL OF LEGAL WRITING 69, 76 (2015).

(a) The illegal aliens who are plaintiffs in these cases challenging the statute may claim the benefit of the Equal Protection Clause, which provides that no State shall “deny to any person within its jurisdiction the equal protection of the laws.” Whatever his status under the immigration laws, an alien is a “person” in any ordinary sense of that term.

Opposition To ‘Illegal Aliens’ Is Opposition To Borders, by Jon Feere, Legal Policy Analyst, Center for Immigration Studies, Daily Caller, 25 May 2016.
Those who are driving the effort to control and contort language in the immigration debate are not truly motivated by the notion that the term “illegal alien” is a pejorative. This is a distraction. The real goal of those demanding that media outlets, courts, and now the Library of Congress supplant accurate legal terminology with activist-created terms is to eradicate the distinction between citizen and non-citizen, between legal activity and illegal activity, between “us” and “them” so that the concept of borders and the nation state slowly slip away. Any official heading an organization or governmental agency who thinks they are being sensitive by bowing to demands to alter their use of language is being played by the open-border crowd...
In reality, we’re a nation of citizens. And as citizens, we have a right to decide who gets to immigrate here, how many people get to immigrate here, and also set the conditions they must abide by if they want to stay. Anything less than that destroys the concept of citizenship and sovereignty. Media shouldn’t help the open-border crowd achieve its goal.
