Among many problems with Trump's citizenship executive order (such as its obvious conflict with the constitution) is a practical one: birth certificates, which are currently the primary proof of citizenship for those born in the US, are issued by state and local authorities. These agencies do not (and aren't equipped to) determine or record the immigration status of the parents.

This means that citizenship would no longer be established with a US birth certificate or any other primary document.

In practice, birth certificates would likely be accepted MOST of the time as establishing citizenship, but those listing parents with "foreign sounding" names would be subject to open-ended scrutiny and investigation. And years later, people born here whose parents are dead or unavailable might have no way to definitively prove that they're citizens.
One of the issues is that for birthright citizenship (as opposed to naturalization), one is not "granted" citizenship through a formal process or application, but rather simply has it from the moment of birth. The first time a person born here has to interact with the federal government to prove citizenship might be years later (e.g., applying for a passport), if at all.

@mattblaze I know a couple people who have had problems with that. They're absolutely citizens, but they have to prove it.

One is even harder - they're citizen-by-adoption-as-a-child. Their foreign-citizen father went back home after divorce with adoptive-mother-that-granted-citizenship. Adoptive mother doesn't want anything to do with them anymore, not even provide basic documentation needed for State Dept to acknowledge their citizenship.

@mattblaze Social Security Numbers are issued at birth, so potentially this could morph into the SSN department needing to know parents SSN numbers to handle the verification. Which would remove the state responsibility for the process.
@mattblaze just checked how and when registration laws were implemented in Germany, where we mainly have that "German is who is descendant of Germans" citizenship.. At the time of the empire, past 1871, there were only some regional laws, which have been unified and implemented for all of Germany in .. 1938

@mattblaze

Something like this occurred in the UK for post-war Caribbean immigrants and their descendants (the "Windrush scandal"). Decades later, the Conservatives introduced retrospective requirements for documentation to prove the right to stay. Something like three documents for every year, continuously since arrival. Many were deported or lost social security because they didn't have documents they were never told and couldn't know they would need. It was (and still is) disgusting.

@mattblaze it's going to be such a huge mess.

Does it apply only to people born after the order or retrospectively? If so, how many generations do you need to go back to prove citizenship? Are locals with generations of assumed citizenship less able to prove their citizenship now than some immigrant who's father has a certificate of naturalisation?

I guess that's the point. It'll only be used to wield chaos on those with the wrong name or skin colour.

@phenidone The order says it applies to people born 30 days after it was signed, FWIW.
@mattblaze ah ok. Slightly less insane and mendacious than I expected they would try.
@mattblaze …which unfortunately is probably the whole point.
@mattblaze that sounds like part of the plan!
@mattblaze Sounds like it could generate another 20 year saga of "Birth Real ID" legislation and compliance debate
@mattblaze Or those with brown skin. Or those whose politics don't align with the administration's. . .

@mattblaze Yes. To inherit my late wife's postal savings account here in Japan, I had to trace her extended family history back to the birth of her father. The full record is a dozen pages long, spanning three major changes to the law and the form of records. Everything was delivered by her home town city hall in response to a single request.

US recording systems are ad hoc and messy by comparison, minimum-passing-effort rather than best-in-class.

@mattblaze

ayup. Completely breaks the system.

@mattblaze that sounds like that's their goal.
@mattblaze There's precedent for this kind of chaos. Thousands of US citizens born in South Texas (including a family member of mine) have been denied passports (or passport renewals) in recent years because of incredibly broad assertions of document fraud by midwives in the 1950s and 1960s, assertions that are very difficult to challenge. https://www.texasstandard.org/stories/thousands-of-u-s-citizens-in-south-texas-have-been-denied-passports/
Thousands Of U.S. Citizens In South Texas Have Been Denied Passports

The State Departments cites charges that some midwives produced fraudulent U.S. birth certificates as far back at the 1960s as the reason for denying passports to many who were born along the Texas-Mexico border.

Texas Standard

@mattblaze

I imagine there must be tons of federal laws, rules and regulations around birth certificates as identification. This must have all sorts of crazy impacts that seem like they could only be handled properly by doing this at the congressional level and rewriting this piece by piece.

A lot of the first administrations changes fall apart during court challenges based on rules and administrative issues. Is this a viable path of attack?
