A statement in the Declaration of Independence confirms that with these statements:
We hold these truths (Natural and Individual Rights) to be self-evident, that all men created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness.
1. Has already illegally worked in the U.S.
2. Is suspected of staying in the U.S after their green card expires.
3. Presumed of having ties to terrorists or criminal organizations.
4. Having been found guilty of a criminal offense.
Hope this helps :)
