The Constitution did provide an EXACT definition indeed in 1790 the first congress stated that a person born overseas to American parents was a natural born citizen.
No. It said the law was going to pretend that person was an NBC, even though they weren't even a citizen under the constitution.
The phrase "shall be considered as" creates a legal fiction. A pretend.
Just like you pretend to know the law.
“The Constitution did provide an EXACT definition indeed in 1790 the first congress stated that a person born overseas to American parents was a natural born citizen.”
And it specified that citizenship descended from the father.
