The term “anchor babies” refers to a child born in the US of an illegal alien, giving the baby’s immediate family members a US Citizen relative that can later file visa petitions for those family members, even if a long way off (petitioner must be 21 ). It also gives the mother a defense against deportation, citing great harm due to separation (The US citizen baby can’t be deported). I believe the term arises from the nautical term “kedging the anchor.”
Hope this satisfies.
