Well done...however, what you have quoted is from:
http://bataiosu.files.wordpress.com/2009/01/barack-h-obama-the-unauthorized-biography.pdf
See page 20 of the unauthorized biography which provides no sources for that information.
Fred,
Many thanks for the correction as to that “Obama file” web site and how the info is set up.
I didn’t realize that not everything in it would have as its source tangible/solid things, such as transcripts or letters from schools.
I will stick to tangible things generated by reputable organizations like INA (docs on 0 SR), educational institutions (docs on 0 SR, immigration rules) , etc.
