College records don’t contain any information on where a person was born. My college transcripts list my address at that time and my grades, that’s it.
If anyone wants to know if Obama registered as a foreign student, the place to look is the federal government to see if he was ever issued a foreign student visa. (F-1 visa). You cannot attend school in the US as a foreign student without a visa and visa records aren’t sealed.
For example, Obama’s father’s student visa files were released under Freedom of Information Act requests.
Just for the heck of it, I checked the on-line application for a local college in my neck of the woods. They wanted citizenship info.
