Thank you for your post--and welcome to the forum :-)
Your current proposed topic "Impact of Islam on Socio-cultural Life of Medieval Kashmir", does that look at Islamic life during medieval times? Can I ask, if that is so, why have you choose medieval?
How about the impact of Islam on socio-cultural life in the 21st century--and then maybe look at different countries--from moderate Islamic state to extremist to liberalist etc.
Or Islam in a communist country? Or look at the progression the impact of Islam in another country, for example Germany---pre WWII, during WWII, post WWII.. etc.
the sky is the limit :-)
enjoy your research
