False dowry and others cases

I am an Indian national on a Canadian study visa. It will take one more year to complete my studies in Canada. My sister in law has filed an FIR on a number of civil and criminal sections on whole of my family including me on false grounds. The chargesheet hasn't been filed yet. We got a notice bail (till the end of mediation) and mediation proceedings for two months but it didn't work out. She is asking for about 1 crore compensation which is not possible to meet. I believe that the chargesheet would be filed soon. As my family believes, most probably the investigation officer won't remove my name from the chargesheet (to get some money or go for big settlement). I fear that if I come to India, I might get stuck in bail proceedings or my passport might be seized for bail or any other worse combination. I can't come to India while my studies are going on. In this scenario, what should my steps be? Can I be served summons to appear in court? How can I counter this order? Should I avoid coming to India till the case goes on? How can I ask the court's permission to complete my studies?
