Babies born to legitimate citizens are OK. Babies born to foreign diplomats should belong to the country of their parent's origin. Babies born to those who enter illegally should belong to the country from which they fled. Those that are born here, regardless, are due safety. Citizenship is gained by following the naturalization policies already in place. I don't see what the fuss is about all of this as we've had many decades to get a feel for the the many complications that can occur. The fuss, IMO, seems to be more about who has voting rights or the other rights afforded to citizens. Throw these sort of matters at our politicians today and all you get is muddy water.
Should a baby born in the US auto become a citizen?
How about if the parents are illegal?
