According to m sister until recently children traveled on their parent’s passport until of age.....Would this fact have any relavance?
Obama was an adult (in college) in 1981. He made the 6-month trip to visit his mother in Indonesia and to go various other places in the Middle East. In one of his autobiographies, he mentions some of these places; I haven’t read the books, but supposedly his destinations included places like Iran, etc. However, some of these places, such as Iran, did not permit Americans to enter with an American passport at that time. Hence, this means he had some other passport.
