I have given birth 4 times and at no time was I ever called upon to write anything on the hospital record. It was done by interviewing me while I was still in the hospital immediately after the birth. Had I given birth elsewhere, the interview would not have taken place in my hospital room, unless it was an emergency and I was rushed to the hospital, just not quite in time. Which would still indicate a birth in the United States. Hospitals know when someone has given birth within their precints - or not. You have to be admitted and your presence recorded. I do not believe Obama's mother could have faked a Hawaiian hospital birth, based on my own (and other's) childbirth experience.
