Your baby was born at a hospital in Long Beach or Los Angeles, you have the California birth certificate in your hand, and you work at your country’s consulate. Until last week the regulation said in plain words that your daughter is a United States citizen. On September 4 it stopped saying that.
The Department of Homeland Security published an interim final rule on September 9, effective retroactive to September 4, that rewrites 8 C.F.R. § 101.3 — the regulation that decides which children born on American soil to foreign officials are citizens and which ones are not. Registration of Lawful Permanent Residence for Children Born to Foreign Government Employees in the United States, 91 Fed. Reg. 57249 (Sept. 9, 2026) (RIN 1615-AD24; DHS Docket No. USCIS-2026-0496). It did not go through notice and comment first. Comments close October 5, 2026, after the fact.
Here is what the rule actually does, who it reaches, and what it does not touch.
What the Constitution requires
The Citizenship Clause of the Fourteenth Amendment: “All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.” INA § 301(a), 8 U.S.C. § 1401(a), uses the same words.
Two elements. Born here, and subject to the jurisdiction. Everything in this fight is about the second one.
The Supreme Court settled the broad question ten weeks ago. In Trump v. Barbara, 146 S. Ct. 2438 (2026), decided June 30, the Court held that children born in the United States to parents who are unlawfully or temporarily present are subject to the jurisdiction of the United States and are citizens at birth. Chief Justice Roberts wrote that a person physically present here is subject to our jurisdiction “unless he falls under one of the familiar exceptions, such as for ambassadors.”
Those exceptions come from United States v. Wong Kim Ark, 169 U.S. 649 (1898), and they have been read narrowly ever since: children of foreign sovereigns or their ministers, children born on foreign public ships, and children of enemies during hostile occupation of our territory. The diplomatic exception exists because a receiving country has ceded a piece of its authority over an accredited envoy. It is a doctrine about sovereign immunity, not about employment.
What the regulation used to say
From January 1982 until this month, 8 C.F.R. § 101.3 drew the line at the State Department’s Diplomatic List — the Blue List. A child born here to a “foreign diplomatic officer accredited to the United States” was not subject to the jurisdiction, was not a citizen, and could be treated as a lawful permanent resident at birth.
And then the regulation said the opposite for everyone else, by name. A child born in the United States is a citizen if the parent is not a Blue List diplomatic officer, “includ[ing], for example,” children born to:
Employees of foreign diplomatic missions whose names appear in the State Department list entitled “Employees of Diplomatic Missions Not Printed in the Diplomatic List,” also known as the White List . . .
and
Foreign government employees with limited or no diplomatic immunity such as consular officials named on the State Department list entitled “Foreign Consular Officers in the United States” and their staffs.
Read that second paragraph again. Consular officials and their staffs. For forty-four years the government’s own regulation told consulate employees that their American-born children were American citizens. That paragraph is the paragraph DHS deleted.
What the regulation says now
The new § 101.3 replaces “foreign diplomatic officer” with a defined term, “foreign government employee,” and the definition reaches four groups: foreign diplomatic officers accredited to the United States; a person employed by a foreign embassy or consulate who is a national of that foreign country; a person employed by a foreign government in an official capacity; and a person employed by an international organization that possesses international-organization immunity.
The operative sentence: “A person born in the United States to a foreign government employee is not subject to the jurisdiction of the United States for purposes of birthright citizenship, unless at least one parent of the person is a United States citizen.”
The rule does exclude some people. Personal employees and attendants of foreign officials are out. So are employees of state-owned enterprises in a status other than A or G, third-country nationals working for a foreign government, contractors of foreign missions in a status other than A or G, and foreign government employees here in a personal rather than official capacity.
The authority claimed is INA §§ 103(a), 101(a)(20), and 262–266, and Executive Order 14418, “Continuing to Protect the Meaning and Value of American Citizenship,” issued August 6, 2026.
Two limits that matter more than anything else in the rule
It is not retroactive. DHS says so directly: “The IFR applies prospectively to children born in the United States on or after the effective date of the IFR,” and “Children born in the United States before the effective date of this IFR are not subject to the requirements of this IFR.” If your child was born before September 4, 2026, this rule does not reach that child, and it does not reach a passport issued under the old regulation.
It is under injunction, and DHS has conceded it. From the preamble: “Given the injunction currently in place in Casa Inc. v. Trump, No. 8:25-cv-00201 (D. Md. Sep. 2, 2026), DHS will not take actions to implement the rule specifically to any member of the certified class, or otherwise conflict with the preliminary injunction, unless and until the government obtains relief from the injunction.”
So this is a rule with an effective date, a live constitutional challenge in front of Judge Boardman in Maryland, and an agency that has already told the Federal Register it will not enforce it against the certified class.
What registration actually is
For a child the rule does cover, registration as a lawful permanent resident is voluntary. It is done on Form I-485 — $1,440 by paper, $1,390 online. That is a registration of a status the regulation says the child already has from birth. It is not an adjustment of status under INA § 245 and should not be prepared as though it were.
If the child does not register, the obligation does not disappear. A person born in the United States who is not a United States citizen falls under the alien registration requirement of INA § 262 and must register when the statute requires it, which DHS is handling through Form G-325R.
The mistakes I expect to see
Assuming the birth certificate answers the question. A California birth certificate proves where the child was born. Jurisdiction is a separate question, and the certificate does not speak to it.
Assuming this only touches diplomats. That was the old rule. The new definition covers a consulate’s locally posted staff who are nationals of that country. Los Angeles hosts the largest concentration of foreign consular personnel on the West Coast, and most of those employees have never thought of themselves as diplomats, because they are not.
Assuming the injunction means nothing has changed. The regulation is on the books with a September 4 effective date. An injunction protecting a certified class is not the same thing as a repeal, and it can be modified, narrowed, or stayed on appeal.
Letting the comment period pass. Comments close October 5, 2026 on docket USCIS-2026-0496. An interim final rule that skipped notice and comment is most vulnerable on the administrative record, and the record is what people build during the comment period. This is the second immigration rule this year to take effect on publication and collect comments afterward — the July asylum-referral rule did the same thing.
Guessing at the parent’s classification instead of reading it. Whether a parent was in A-1, A-2, G-4, or something else on the date of birth is now the fact the whole analysis turns on, and it is written on documents the family already has. The same discipline applies to reading a class of admission on an I-94 — read the record, do not remember it.
What to do this month
If a child was born to you in the United States on or after September 4, 2026 and you or your spouse worked for a foreign government or an immune international organization on that date, pull the parents’ visa classifications and I-94 records for the date of birth and get the file reviewed before you apply for a passport or a Certificate of Citizenship. The order in which you file matters.
If your child was born before September 4, 2026, the rule does not apply to that child. Keep the documents that establish the parents’ classification at the time of birth anyway.
If you are a foreign mission or an employer of A or G nonimmigrants, the population you need to identify is small, specific, and identifiable right now.
