My k3visa rejected 10 years back, but now i am going to india for H1 stamping. is there any possibility, they rejected stamping?

There is always a risk of a denial. No attorney can guarantee a risk free immigration process.

Honest attorneys advise you without telling you what you want to hear, they advise you as realistically as possible so you may form an educated opinion. I agree with Counsel Ferrari, there is no guarantee of any legal outcome and that that you will not receive a denial.

That risk always exists. Consult with an immigration attorney before you travel.
