I believe that it is easy for illegal immigrants (and foreign travelers in transit) within the US, to obtain US citizenship for new born child/ren.
To preserve the country economic, cultural, ethnic, religious and political withstand integrity, I support a similar legislation Immigration / Citizenship Law as in other countries:
a-) where a new born with BOTH parents in illegal or in transit migration status be not longer granted US citizenship, but, instead a document to help their parents register and claim their nationality of origin for the baby/ies;
b-) further, if any of the parents is the recipient of a "green card", extend a "green card" to the new born;
c-) or, if it happens that any -or both- of the parents is a US citizen, then extend our citizenship to the newborn/s.-
