Marshall Island pregnant woman coming to Hawaii to give birth and then to give away the baby for adoption reminds me of what the cuckoo bird does.  It lays its egg in the nest of a different species, alongside the eggs already rightfully there.  Then the nestmother sits on all the eggs and feeds all the hatchlings until they fly off.  Cuckoo gets its genes propagated while making somebody else do all the work.  It's similar to Korean and Mexican women giving birth to "anchor babies" in America, except that the Koreans and Mexicans keep their babies and take them home.  Then later the grown-up anchor baby (who is American citizen) brings parents to America.  Either way, Marshallese and Koreans and Mexicans have safe harbor in America while getting around immigration laws.
