Neha,
you have a very good horoscope with great potential. Currently Ketu Mahadaha is operating and Jupiter Antradasha from 23/4/2017 to 30/3/2018. Jupiter being cuspal sublord of 10th house is good for you and being in 12th house in Chalit can take you abroad (Jupiter is in star of Rahu which is in 9th house). Changing job in this period will not get you a good job.
Ketu-Saturn period from 30/3/2018 to 9/5/2019 and Ket-Mercury period from 9/5/2019 to 5/5/2020 will be excellent for job change + will bring better increments in new job.
Extraordinary period of life will start in form of Venus Mahadasha in 5/5/2020 for 20 years and Venus placed in 10th house will bring you great success and stability given Venus is in star of 9th lord Mercury and in sub of Venus(lagna lord in 10th house is a rajayog)
You will find more success abroad and May god bless you!
