Indonesia didn’t permit dual citizenship and there is no record of Obama renouncing U.S. citizenship. He was six years old when his mother and he moved to Indonesia in October of 1967. Indonesian law required a child to be “less than five” in order to become Indonesian citizen via an adoption. No record of an adoption has surfaced either.
There was a change in U.S. law that required minors to have their own U.S. passports.
“Minors Under Age 16
Minors under age 16 must apply in person
All minors regardless of age, including newborns and infants, must have their own passport when traveling internationally by air.”—U.S. Department of State. http://travel.state.gov/passport/parents/parents_6061.html
If Barry Soetoro didn’t maintain U.S. citizenship, he would have needed an F-1 Student Visa to attend 5th grade through 12th grade at The Punahou School, and also at Occidental College, Columbia University and Harvard Law School.
There is no record of him ever being issued a foreign student visa and visa records are in the public domain, available under the Freedom of Information Act.
Stanley Ann Dunham returned to the US in October, 1971 and on arrival in Honolulu was told that her US passport had expired in August, 1971. She was allowed into the US and in January, 1972 was issued a new US passport.
If she was an Indonesian citizen, it was for two months.
Barak Obama returned to the US in June/July of 1971, if he had a US Passport it would have expired in August, 1971.
In September, 1967, the State Department investigated the citizenship status of Barack Obama as part of an investigation of Lolo Soetoro’s status.
W. L. Mix wrote that “The person in question is a United States citizen by virtue of his birth in Honolulu, Hawaii, Aug. 4, 1961. He is living with the applicants’ spouse in Honolulu, Hawaii. He is considered the applicant’s step-child, within the meaning of Sec. 101(b)(1)(B), of the act, by virtue of the marriage of the applicant to the child’s mother on March 5, 1965.”
The section of the 1952 McCarron - Walters Act stated by Mix reads:
Section 101 (b) As used in titles I and II -
(1) The term “child” means an unmarried person under twenty-one years of age who is -
(A) a legitimate child; or
(B) a stepchild, provided the child had not reached the age of eighteen years at the time the marriage creating the status of stepchild occurred; or
(C) a child legitimated under the law of the child’s residence or domicile, or under the law of the father’s residence or domicile, whether in or outside the United States, if such legitimation takes place before the child reaches the age eighteen years and the child is in the legal custody of the legitimating parent or parents at the time of such legitimation.
So in 1967 Obama had not been adopted by Soetoro and was referred to as a “stepchild”.
If he was adopted after 1967, he would have been to old to acquire Indonesian citizenship automatically by adoption and would have had to go through the Indonesian naturalization laws when he turned 21.
