you are under Rahu Mahadasha from 19/8/2013 and Rahu-Jup period (1/5/2016 to 24/9/2018) and Rahu-Saturn period (24/9/2018 to 31/7/2021) are not good for acing competitive exam such as civil services at all (Saturn would be worse).
Rahu is in 3rd house in Chalit shows local/short travels but foreign settlement is unlikely given Rahu is in nakshatra of Mars and has Venus as sublord (Venus being lord of 4th house/nativeland).
Engineering would be best for you as Rahu, Mars and Ketu are strong for you (Moon in 10th house in Chalit and Sun aspecting 10th house shows inclication to govt job). Below periods will be good if you still want to give IAS a short before age of 30
* Rahu-Mer (31/7/2021 to 18/2/2024) is moderate: year 2022 will be good
* Rah-Ket (18/2/2024 to 7/3/2025) would be very good
Period from 18/2/2024 to 19/8/2031 will be good and overall you can be a good administrator!
