All the old passports are valid until november 2015 or even if yours expires after this date,it won't be a problem now though since its valid but 2015 would be around soon and you may need the new one. I went in for the new passport even I still have a valid old one just to be safe,who knows they might insist on the new one.
Sorry, but non-bio metric passports are no longer accepted by the US embassy. even though the government says we have until 2015, the US embassy will always ask you to get the new one before the issue the visa. I know this for a fact because it happened to me when I went to renew my child's visa. I hope this helps?
