“and subject to the jurisdiction thereof”

Right. An important clause. But it says nothing about those slaves parents. Again the NBC for BO is a seperate issue. If Obama was born in HI, he’s a US citizen at birth (albeit perhaps he was a dual citizen.) But he may not be/have been a NBC. The SCOTUS needs to rule on that.
There’s a move afoot in CA and elsewhere though to challenge the citizen status of anchor babies. This might affect this debate in the future (of who’s a citizen at birth and who a ‘natural born citizen’ is.)
