Being undocumented is a civil offense, not a criminal one. The distinction is relevant, and important.
8 U.S. Code § 1325 - Improper entry by alien
(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.
For what it's worth, when denaturalization came up in the first Trump presidency, SCOTUS threw them out of court because they deemed the word "material" as... very material. Though who knows if they'll change their tune this time.
Have you EVER been a member of, involved in, or in any way associated with any organization, association, fund, foundation, party, club, society, or similar group in the United States or in any other location in the world?
And then demand dates, locations, roles, etc for each and every time you have?
I'm sure you could torture that into applying to that situation, but at least on a very plain reading it doesn't sound like it applies generally to those people.
That doesn't make sense. If you overstayed the visa then you (probably?) entered legally, not illegally. Did you mean something else?
Was trying to figure out a succinct way to say that and instead just butchered it. Words are hard.
Stepping past the direct offense of being here, one must ask how are they supporting themselves financially? Assuming they are workers, they’re either not paying taxes (a crime) or stealing the identity of a citizen in order to fool an employer. Now they are at least paying taxes, but they’ve victimized a lawful resident or Citizen. This is far from a victimless crime, it took my mother two years to fully clear her name after this occurred to her identity. The IRS and credit agencies are not very understanding.
