So where and when did Obama natuaralize?
Obama went to Indonesia in 1981 (he was twenty years old) before he traveled to Pakistan. Now we know Obama’s mother was living in Hawaii in 1981 after viewing the Soetoro divorce record.
So, Obama went to Indonesia before he traveled to Pakistan to renew his Indonesian Passport. Consequently, we can reasonable conclude Obama naturalized as a U.S. Citizen in 1982 or 1983.
