Obamas grandmother got his certs. He was not born in Hawaii. His sister 100% born in Indonesia has one just like it. You do not have to be born in Hawaii to have a colb. To qualify for Hawaiian Homelands program you have to be Hawaiian. The State will not accept the colb as proof of Hawaiian birth.
Hawaiian Home Lands is a program for indigenous Hawaiians. You need to prove that you have ethnic Hawaiian ancestry, not that you were born in Hawaii. That's why a COLB is irrelevant to that program.
I haven't seen a copy of the sister's COLB; do you have a link to it?
And his daddy was NOT an American
