For this query answer rests in future and right now, nothing can be said about eligibility policy UPSC may adopt while notifying for Civil Services Examination 2016.
Prospects for Age relaxation from 30 to 32 next year i.e. for CSE 2016 are doubtful as this relaxation was only for two years; but, we can hope that five years age relaxation for candidates domiciled in the state of Jammu & Kashmir should continue.
Even if, this relaxation stays, you will be eligible to appear in CSE 2016.
You should not have any apprehensions and you should prepare diligently so that you are able to accomplish task in this attempt.
