You are a Civil Engineer in your profile and you are going to take 5-6 months leave? That is really funny!!!Your company might have renewed your RP in August 2009 by giving some fine and that is why the expiry date has moved to August 2010. If they had renewed it only last week then the expiry date would have been moved to December 2010. You cannot change the expiry date of your RP to enable you to take 6 months leave. There is only one option now for you. Request your company to give leave from March instead of April so you can take 5-6 months leave.
