The practice of 'birth tourism'does not violate federal law but there are dubious ethical issuessurrounding the practice.
It is written into the U.S.constitution under the 14th Amendment that those born in the U.S. will begranted citizenship.
According to studies on 'birthtourism' it is popular with wealthy mothers-to-be from several countriesincluding China, South Korea, Taiwan and Turkey. Although most mothers returnhome after giving birth, because their child has been born in the U.S., itallows them to get around strict international rules for studying at Americancolleges.
Once they turn 21, the childrencan also petition for permanent residency for their parents through familyreunification.
The government estimates thatthere were 7,462 births to foreign residents in 2008. The Center forImmigration Studies said close to 40,000 births each year are to 'birthtourists' - however that number could be as high as 200,000.
