"Do I have to go to police station or can i request that the detective come to my home?"
*** Of course you don't have to go to them and can 'request' that they come to you. However, you probably won't like the 'terms' that they impose if they decide that they need to question you further.
There are at least 17 lawsuits (!!) filed in various courts, including the US Supreme Court, asking if Obama is a natural born citizen (as req'd by Art II, Sec 1 of the US Constitution).
Why has he spent over $1.7M in legal fees to block disclosure... rather than spend $12 for a VALID birth cert to settle the matter? The 'certificate' he has presented doesn't qualify to get a drivers license, wouldn't allow a child to qualify for Little League, or for a real citizen to get a US passport!
