Hawaiian law, at the time of Obama’s birth, allowed for FOREIGN born baby’s to be registered in Hawaii via a ‘Certificate of Live Birth’: “[§338-17.8] Certificates for children born out of State ” http://www.capitol.hawaii.gov/hrscurrent/Vol06_Ch0321-0344/HRS0338/HRS_0338-0017_0008.htm
As I explained in a previous post, that law was passed in 1982.
