I'm not sure about the context of your post. You may want to consider clarifying the above post as it seems to have combined things or left out things (or both) in such a way that it is not representative of how the State Department is currently handling determinations of US citizens born abroad this year, last year, and for some years before.

Those determinations as you know are done under the INA, as revised, in conjunction with material submitted by such children's US parent(s).
