In the mainstream DC comic universes, did the Kents legally adopt Kal-El upon finding him, or did they just take him home and start raising him without bothering to tell the government? Or did they claim he was their birth son? If he was legally adopted, what was their cover story for finding him? As an extension of that, is Clark officially a U.S. Citizen, by adoption?

    Clark wouldn't be able to have a driver's license if he wasn't registered. They probably said he was their biological son and filed the paperwork.

    There is about a 2% chance that Superman is a natural born citizen of the United States, i.e., if at the moment he was born, Krypton was directly above U.S. territory, which covers about 2% of the globe. As far as I know, in the 1930s there was no upper limit to national sovereignty. The 14th Amendment applies to "persons" born in the United States; Superman is certainly a person.

    @SJuan76 The traditional doctrine holds that property rights extend downward to the center of the earth (not the antipodes) and upward to infinity. As far as I know that traditional doctrine still held sway in the 1930s when Superman was born; the 100 km limit had not been proposed yet, and there were no artificial satellites in orbit.

    @MikeScott I'm not a lawyer, but as I read it, the 14th Amendment forbids a State to "deny to any person within its jurisdiction the equal protection of the laws." No mention of humans or non-humans, just persons. I don't believe there has been any court case testing whether an intelligent extraterrestrial is a "person". (I'm reminded of the Heinlein story where a court has to decide whether an uplifted chimpanzee is a man.)

    @Paul Because Clark Kent needs it to work various jobs and not stand out. Also, there's the whole legal hiring process.

I feel compelled to remind everyone that I am not a lawyer, and especially not an immigration lawyer. On the off chance that you find an abandoned space-baby by the side of the road, do not take this as legal advice for how to proceed.

Clark would be considered a natural-born citizen...

In the New 52, the current DC mainstream universe, it's not clear whether Clark was legally adopted, or passed off as the natural born son of Jonathan and Martha Kent. His origin story is told in Action Comics 5, where it's revealed that the Kents discovered Kal-El's crashed ship, and passed off a deformed calf as the occupant to investigating government officials:

enter image description here

enter image description here

Jon: Me and the missus found something over yonder when we come by before. Take a look in back. I'm guessing there must be some kind of reward, right? You can have my name, telephone, anything you need. But this ain't about chemicals, and we all know it. Check him out. You'll see. Reckon I found me a spaceman.

A later panel reveals that, shortly before discovering the ship, the Kents were interviewing at an adoption service, who gave them bad news:

enter image description here

Martha: -- And at first, we thought it was the answer to our prayers. But, after the miscarriage... Well, Jon and I never really thought seriously about adopting before, but there are so many unfortunate children in the world who could use a loving home...

Strommen: That's certainly true. And you do seem like a lovely couple. However, I should warn you up front that adoption is a long process, too. There are referrals, screenings, home visits, court hearings... It can take years to find an appropriate match, and the fees can add up to even more than what you spent on your in vitro procedure.

So I'm inclined to suggest that they just passed him off as a miracle, in which case he'd be a natural-born citizen as far as the rest of the world knows.

However, even if he was presented as a foundling and legally adopted1, according to 8 USC 1401, he would still be considered natural-born as long as nobody blabbed about his alien heritage:

The following shall be nationals and citizens of the United States at birth:


(f) a person of unknown parentage found in the United States while under the age of five years, until shown, prior to his attaining the age of twenty-one years2, not to have been born in the United States;

As long as everybody keeps their mouths shut, he's a natural-born citizen either way. It should be noted that this law (called the Foundling Statute) is basically never used, its few recorded successes quite fittingly map to Clark's situation; again, assuming nobody ever finds out that he's actually an alien.

This has been fairly consistently true of Clark throughout his publication history; Golden Age and Silver Age Kal-El were both legally adopted from an orphanage (see footnote 1), in which case the Nationality Act would qualify him as a citizen, assuming nobody knew that he was an alien3. Most post-Crisis versions gloss over this detail, so either explanation above could qualify, with the same result.

...but probably illegally...

Note that, in virtually all versions of Clark's backstory, it would almost certainly be massively illegal for him to be granted citizenship in this way; since every version of the story has the Kents aware that Clark is of extraterrestrial origin (if there's an exception, I'm not aware of it off hand), withholding that information to get him citizenship would constitute immigration fraud4. I have no idea what would happen to them if the truth ever came out, but I'm sure it would not be good.

I'm also not sure what would happen to Clark, but I suspect it would depend greatly on the preferences of the courts; perhaps they opt to grant him citizenship5, or perhaps they opt to deny citizenship but grant refugee status6, or perhaps they deny his personhood and send him to Area 51, or something else entirely.

...and Superman is different

As long as nobody knows that Clark Kent is Superman (or, at least, as long as the government doesn't know), they're separate legal persons, and would have different immigration statuses; everybody already knows that Superman is an alien, so the Foundling Statute doesn't apply to him, and his immigration status is a matter for the courts to decide. As other answers have noted, different comics writers have handled this in different ways.

It would be still another matter if Clark's dual identity became public knowledge. In that case, it would again likely be a matter for the courts to sort out.

1 Which was his original backstory, according to Action Comics #17:

enter image description here

As a distant planet was destroyed by old age, a scientist places his infant son within a hastily devised space-ship, launching it toward Earth!

When the vehicle landed on Earth, a passing motorist, discovering the sleeping babe within, turned the child over to an orphanage.

2 Note that the original version of this statute, the Nationality Act of 1940, did not have this "until the age of 21" restriction; under those terms, you're a natural-born citizen until it can be proven that you were not born within the United States. As best I can tell, this limitation was added in 1952, but again I am not a lawyer

3 Which, despite the fact that he was found in a crashed spaceship would seem a sensible assumption. No commentary on how incredibly dumb Golden Age and Silver Age civilians were.

4 It should be noted that the current wording of the Foundling Statute specifies that a foundling's non-American birth must be "shown"; some, such as lawyer James Daily of "Law and the Multiverse", could make the argument that "shown" would mean "legally proven", which might give the Kents a break, depending on the adaptation and the weight of the burden of proof required

5 Assuming they first grant him personhood, which our friends at Law.SE believe is likely

6 It's not like they can deport him back to Krypton, after all

7 The original, not the New 52 one. I hate it when they restart numbering like this

    @nedlud So long as he never tries to run for President. In all seriousness, that isn't necessarily too tremendous of an issue; children are delivered in the home all the time (my nephew was, in fact), so they could just register Clark as a new birth. How their neighbours react is never discussed, so far as I know Commented Apr 14, 2016 at 0:17

    Clark Kent would need some kind of ID so he could get a drivers license, open bank accounts, etc, but the home birth example you give is good. The Kents' could just register his birth the way home birth families do.

    @nedlud Interestingly, one of Superman's post-Crisis backstories (John Byrne's The Man of Steel) sidesteps this issue: after finding baby Kal-El, a freak snowstorm traps the Kents in their farmhouse for months.

Yes and No.

In a strictly legal sense it's worth mentioning that all of the early (Gold and Silver age) comics agree that Clark was originally found by the Kents, then put up for adoption and then legally adopted by the Kents from the Smallville Orphanage.

As an adopted orphan, Clark will be given a new birth certificate, along with an adoption certificate. Given that the Kents are both (presumably) US citizens, that would make Clark automatically a US citizen.

The wrinkle comes from the fact that Clark isn't human and hence isn't accorded any rights under US law. This leaves us with the unpleasant fact that he's not a US Citizen because citizens must be people and he isn't. His legal identity is a house of cards. Push it (even slightly) and it'll fall down.

    Do you have a cite for the assertion that Clark has no rights under US law? I'm not a lawyer, but I'll bet that there has been no U.S. court case testing the proposition that an intelligent humanoid alien is a person. But maybe you can find a definition of "person" in U.S. law.

Two bits of history that may or may not still apply, but at least shown it's been considered on occasion.

During the Byrne era, Superman's ship was a gestational device, an artificial womb, if you will. Martha Kent broke it open to "save" the baby. Superman decided years later that this meant that he was "born" here on Earth, and considered himself as such. Also, after said discovery, the area around Smallville had a massive blizzard, and the Kents decided to lie and tell people Clark was their natural child, born during the blizzard.

As for citizenship, back in the silver age they did an origin story where the UN declared unanimously that Superman would have simultaneous citizenship on all countries of the Earth, thus making him a citizen of the world, as well as allowing him to enter any country with impunity to engage in a save.

  • Also in the Byrne era, there was a "What If" story where Clark Kent -- publicly outed as Superman -- runs for president in 2000. The question of his origins was brought up, but after his "gestational matrix" was examined by experts, the courts declared that he'd been born in Kansas and was eligible to be elected.

If Clark Kent alias Superman is considered a national of the country of Krypton then he is eligible for refugee status on the grounds that he is unable to return to Krypton. Since he would be applying from within the US he would be considered an "asylee" or asylum seeker. Because Krypton no longer exists he would have a good case to be granted asylum, even if the government opposed it. Once granted asylum he could then apply for a Green Card and subsequently become a citizen.

Of course when passing for human as Clark Kent he can't claim his extraterrestrial origin as a defense against deportation, but neither is anyone going to be able to show that he is not a natural US person. The irregular nature of his adoption is not relevant here. The Kents can tell the truth, or whatever part of it they wish (e.g. "we found him abandoned with a note saying 'please look after this boy'"). As part of deportation proceedings the government has to be able to prove where you came from so that they can deport you back there: they can't just shove you over a random border post.

Hence Clark Kent is safe from deportation as an illegal immigrant either way.
