In other words, your suspicions have no basis in fact.
Of course his mother and grandmother had every reason to lie about his place of birth,
No they did not, for reasons stated below.
Tell me how he could be naturalized if born in 1961?
Secton 1431 of the US immigration code, originally adopted in 1952:
a) A child born outside of the United States automatically becomes a citizen of the United States when all of the following conditions have been fulfilled:
(1) At least one parent of the child is a citizen of the United States, whether by birth or naturalization.
(2) The child is under the age of eighteen years.
(3) The child is residing in the United States in the legal and physical custody of the citizen parent pursuant to a lawful admission for permanent residence.

How long would it take?
It would be automatic as soon as brought Bambi back to the US and established residency.
What would having a foreign father from Kenya have to do with the procedure?
Nothing.
Maybe the same reason Obama won't show his real long form BC and College Records, he can't.
That doesn't make any sense. He's not committing fraud by declining to show you either.
Look at Stanley Ann's divorce filing and tell me if she committed fraud?
I see no reason to believe she comitted fraud in that filing. What makes you think she did so?
Did their marriage application show Obama Sr was already married? Why not?
Most likely because his first marriage was a tribal one not recognized by either Kenyan of US law. Either that, or Obama Sr. was hiding his first marriage from his wife and, being a polygamist, did not want to get a divorce.
In that case, it would be Obama Sr. committing fraud, not Stanley Ann. And he would have a reason to committ it, unlike Stanley Ann.
Second you ignore once again the Kenyan father who would have to acquiesce to his son living in the USA.
You also never answered what evidence is there that Obie was born in any hospital?
