She could get married latest by end of 2018 and before that she will get a job too not much matching with her potential. More work and less returns. If you are interested you can come for a scientific evaluation of her horoscope after reading my blog navagrahastro.blogspot.in
your daughter’s 7th house of marriage and 8th house of in laws are two most prominent houses in her horoscope. Reason for delay in marriage is
* Jupiter as 7th lord and 10th lord is retrograde in ascendant in nakshatra of Rahu and with Rahu as sublord making it weak as Rahu is placed in 8th house
* Saturn in 7th house delays marriage and adviced to get married around 31 years or so . Also Saturn is afflicting lagna lord Mercury along with Mars is delaying marriage
She is currently under Jup-Jup period from 2/10/2016-20/11/2018 and it shows currently there is a secret love affair going. Saturn return in 7th house from Oct 2017 onwards will open doors for marriage and good chances in Jup-Jup-Moon (7/4/2018 to 11/6/2018) or Jup-Jup-Mar(11/6/2018 to 26/7/2018). Chanting Jupiter Beej mantra 21000 times in 21 days will help massively.
Doing her own business/consultancy will work better. Carrier will get better from Jup-Sat period i.e. 20/11/2018 to 2/6/2021 and will continue well in Jup-Mer period 2/6/2021 to 8/9/2023.
