YOu are not going to be admitted to the US in B-1/B-2 status for a year.  6 months is the maximum period of authorized stay and even that is discretionary with the port of entry officer, based on the interview conducted at the time of entry as to what the purpose of your entry is.  B-1/B-2 is for vacation , tourist type of travel and it is not likely that you will be granted the entire 6 months stay for such reasons.
