Your yogarakara Mercury mahadasha has started from 5/8/2015 and Mercury placed in 5th house in star of Ketu and in its own sub will be excellent for career progress/success.
1) Mercury-Mercury period from 5/8/2015 to 1/1/2018 which is great for career but not good for foreign settlement
2) Mercury-Ketu period from 1/1/2018 till 29/12/2018 and this will be decent for career and Ketu placed in 4th house in nakshatra of Jupiter with Rahu is ok for short distance travels but will not let you settle abroad
3) Mercury-Venus period from 29/12/2018 to 29/10/2021 is good for foreign posting/job/transer as Venus is in nakshatra of Rahu with Moon as sublord.
You will have lot of travels but foreign chances of foreign settlement permanently are not that high (Mercury as lord of 2nd and 11th house is placed in 4th house (denoting homeland) in Chalit)
