I do not see major improvements before February 2018. Although you can get a change before that but it not be what you totally expected. The possibility of making a wrong decision during this phase is very strong. I suggest that every step you take you should be careful and do not take any hasty decisions.
As per your horoscope your Lagan is Libra and Saturn is the Yogakarka planet. You should do Shani puja every Saturday for benefits.
