If they were green card holders awaiting citizen ship and born in the U.S or in U.S territory or flagged entities, then yest of course their child is a NBC.
One of the theories I’ve been reading is the two bites at the apple theory. Cruz had two bites at the apple, with the first bite being Canada citizen, therefor he is not NBC.
No, they were both Cubans.
of course their child (Rubio) is a NBC an anchor baby.
Of course even that's debatable, as the 14th amendment was not intended to allow illegal aliens and tourists to create US citizens at birth, but rather to give citizenship to freed slaves and their children.
