And the sooner you ascertain that the child is eligible for citizenship, the better. It is not as cut and dried as some people may think.
I agree with that. Although crossing the US/Canada border was pretty easy up until 9/11.
The correction I offered was that Cruz doesn't become a non-citizen if his his mother failed to register his birth at the US Consulate, which is what your statement, read literally, implied. You said she had to register his birth at the consulate to convey citizenship.
Would you consider your Daughter a naturalized American citizen or Native born?
