Cuttoff this year is expected as per 2017. So its difficult to get a govt seet in haryana with 550 marksm  Bt you can try as per all india quota in other states. 

Hi Himanshu,
With the marks of 550/720 in NEET 2019 your rank will be anywhere around 6,700-8,000 which is good enough if you have the state domicile in the state of Haryana and can apply for the 85% State Quota seats. Looking at last year's cut-offs for UR category in Haryana, almost all colleges had cutoffs below 550 which is good, the lowest being Pt Bhagwat Dayal Sharma Post Graduate Institute of Medical Sciences, Rohtak for the marks of 486. I believe you have a seat at Haryana confirmed with the marks you've obtained.
Congratulations and good luck.
