South Africa's one million invisible children without birth certificates

For reference, the US has procedures for this: https://www.usa.gov/citizenship-no-birth-certificate because people without birth certificates are still somewhat common, even children.

Vermont didn't require it until 1955!

My dad was born in the Philippines in 1939. He came over to the U.S. on a Taiwanese passport in 1959, part of a group of students that MIT imported from the Philippines based on letters of recommendation from their Atomic Energy Commission, and then bounced around on various visas for a decade. Finally got citizenship upon marrying my mom in 1971.

When McCain was running for president, there was a big court case about whether being born in the Canal Zone (a U.S. territory) qualified as being a "natural born citizen". And I made the connection - "Wait. The Philippines was a U.S. territory in 1939. Shouldn't dad have had birthright citizenship?"

Moot point by then, he'd already been a citizen for ~40 years, and died the next year. But it was wild to think that the 10+ years of immigration hassles were basically due to an administrative fuck-up, and that legally, he should have had citizenship all along. The process you link wouldn't work for him, either, because the Philippines is not a U.S. territory now.

This is getting off topic but I do not believe that the Commonwealth of the Philippines was legally/formally a US territory in 1939. It was a protectorate whose foreign affairs were administered by the United States, but it had its own government/constitution that was formally independent and administered by Filipinos. It was more like Cuba than Puerto Rico in the context of the Spanish American war.

Being a territory doesn't mean you become a citizen in any case. American Samoans are not citizens, nor are they entitled to bypass the naturalization process if they wish to become one.
