It may have been a convenient move to put someone other than Barack Obama Sr. on that birth certificate.
It was in the Spring of 1961 that Obama Sr’s foreign student adviser called immigration officials and expressed concern that Obama had recently married a young woman named Stanley Ann Dunham. The advisor, Sumi McCabe, was concerned about the extension of his student visa in April 1961. She knew about Obama Sr’s Kenyan wife, Kezia and his sexual promiscuity on campus. This effort by McCabe put Obama Sr in a panic. It was then that Obama Sr chose to hide his relationship to Stanley Ann and his fatherhood to Baby Barack in order to keep his student visa. Perhaps it was an effort to make sure the INS did not think, when they discovered that Obama Sr. and Dunham were not living together as husband and wife, that their marriage was a sham set-up for immigration purposes. If the INS was convinced that idea was true, Obama Sr. would have been deported and lose his ability to finish his degree.
I think the long form birth certificate had another man listed as the father. As for the place of birth, I think it is hard not to think Kenya was the place of birth where Obama Sr took Stanley Ann to get his father’s blessing. The separation demand by his father, Hussein Onyango Obama, became a huge complication towards his original plan to live with his wife and son in Hawaii while he finished his studies. It would have made his requests for a student VISA easier.
The accusations of his bigamy were the final straw and he had to distance himself from Stanley Ann with every effort. The birth certificate was one such effort.
With minor corrections, they could be twins:
