Two websites are advertising services to Chinese and Japanese women to have their babies in the CNMI in order for the children to gain U.S. citizenship.
The cost for the service is between 15,000 and 40,000 thousand US dollars.
Both saipanbaby.com and babysaipan.com list the 14th Amendment and birthright citizenship as reasons to have babies in the Commonwealth.
Babysaipan.com says once 21 years of age, children can help their parents gain citizenship.
Several "Chinese consultants" are also listed on the Web site, including Yang Baby, which helps Chinese women, for a fee, to have children in the U.S. or Canada.
Saipanbaby.com offers similar services for 60 days, ranging in cost from 15,000 to 40,000 US dollars.
Melvin Grey, director for the CNMI's Division of Immigration, said the practice of providing services for women to have their babies in the CNMI is fairly common.
He says under the 14th Amendment there is nothing the CNMI or United States Immigration officers can do as it's not illegal.
The Commonwealth Health Center and Department of Public Health said it did not know there were Web sites advertising the services.
Two similar Web sites, advertising services to Korean women to have babies in Guam, were shut down last week.
