A naturalized U.S. citizen living in the Middle East told the Hacking Immigration Law live show that her husband — a natural-born citizen — took a second wife a year ago, after she had already naturalized. She wanted to know whether that puts her citizenship, or his, in jeopardy.
mic What the Attorney Says
“It all happened after you got your citizenship. So, I think we’re fine.”
Timing is the whole answer. Denaturalization under INA § 340 — 8 U.S.C. § 1451 — reaches only citizenship that was “illegally procured” or obtained by “concealment of a material fact or by willful misrepresentation,” both measured as of the moment of naturalization. A marriage that did not exist on the day she took the oath could not have been concealed then, so there is nothing in the record to reopen. The polygamy inadmissibility ground at INA § 212(a)(10)(A) — 8 U.S.C. § 1182(a)(10)(A) — bites only on someone seeking a visa or admission as a practicing polygamist, which describes neither of them.
mic What the Attorney Says
“From an immigration standpoint … there’s nothing they can do to him.”
The child from the second marriage is a different statute. A child born abroad and out of wedlock to a U.S. citizen father can acquire citizenship at birth under INA § 309 — 8 U.S.C. § 1409 — but only if the father met the physical-presence transmission rule of INA § 301 — 8 U.S.C. § 1401 — and the law’s added conditions are satisfied: a blood relationship proven by clear and convincing evidence, a written agreement to support the child until age 18, and legitimation or acknowledgment before the child turns 18. None of that is automatic, and someone has to run the analysis before claiming a passport, a consular report of birth abroad, or a Form N-600 certificate of citizenship.
mic What the Attorney Says
“I’ve never researched the issue of a polygamous child born outside the United States to a natural-born US citizen. I just don’t know the answer.”
The reassuring part is narrow but firm: nothing that happens in a citizen’s personal life after the oath reopens the naturalization itself. Denaturalization turns on how the green card and the citizenship were won — the same lens that makes a hidden child surface at the N-400 or a misstatement get scrutinized as a false claim. What comes after the oath is a question for the next generation’s paperwork, not this citizen’s.
