The US constitution states that
All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and the State wherein they reside.
Does this mean that anyone who is born in the US is automatically a US citizen, whether they want it or not? Or does this amendment just offer the possibility of requesting citizenship?
In other words: is there an action to be made in order to become a US citizen when born in the US (and therefore one is not before this action is performed)?
Note: this question is different from another one which deals with the "and subject to the jurisdiction thereof" part. Mine is about the automatism (or lack of) of the acquisition.
