First of all it is instructive to clarify the difference between immigrant and alien. An alien is someone who is a citizen of a foreign country. An immigrant in a country is someone who has relocated there from another country. An immigrant may or may not be an alien.
If the immigrant has applied for and received citizenship, then they are no longer an alien. An alien is subject to host country laws regarding non-citizens. These laws require registration and documentation defining their status while they are in the host country.
Those who sneak into the country are referred to as “entry without inspection” (EWI). Others enter with legal documentation and then violate the terms on which they have been admitted. Both types of illegal immigrants are deportable under Immigration and Nationality Act Section 237 (a)(1)(B) which says:
“Any alien who is present in the United States in violation of this Act or any other law of the United States is deportable.”
If you have evidence of illegal immigration, you are encouraged by the authorities to report illegal immigrants by contacting the main DHS Hotline for assistance at (866) 347–2423, or the Border Patrol Sector where the illegal aliens are located and ask them to investigate further.
Our laws also hold that even lawful permanent resident aliens (those with a “green card”) can be deported if they are convicted of committing crimes.
The Department of Homeland Security still doesn’t have a way to report illegal aliens over the internet. But the Federal Bureau of Investigation does. All Special Agents of the FBI now have the power to enforce immigration law. You can report illegal immigrants by calling or writing one of the FBI field offices.
All male illegal aliens, as well as male permanent resident aliens, ages 18 through 25 are required by Federal law to register with the Selective Service System. If they do not register, they can be prosecuted for a felony and fined up to $250,000 and/or imprisoned for up to five years. They may also be denied U.S. citizenship. You can also report draft registration violators to the FBI.
Many Illegal aliens and criminal alien residents are guilty of some type of fraud against the Social Security system. For many false documents is a way of life. The Office of the Inspector General of the Social Security Administration operates a fraud hotline for reporting misuse of social security cards and false statements on claims either by employers or employees.
The greatest incentive for illegal aliens to come to the United States is to find work. If there are no employers willing to hire them, then the flood of illegal aliens will subside.
From the Immigration Reform and Control Act of 1986:
It is unlawful for a person or other entity to hire, or to recruit or refer for a fee, for employment in the United States an unauthorized alien. Violators are reported to the regional Immigration and Customs Enforcement office.
