I just found that my exwife use me to get her green card,she accused me to abuse her,and I went to criminal court for about 7 months,to proof that she was lie and a jury found me no guilty,she use all these to get her green card,how I can report or stop all this pain that she did with me?? thank you

Well reporting her will not stop the pain, merely moving on with your life, no contact with the ex, and starting a new life, friends, activities and more will be the only thing to make the pain less.

This is the phone to report 1-866-347-2423
But report and let it go, I will say most likely they won't do anything, esp if she already has her card, with 1/2 of all marriages ending in divorce she can just say it was all you. But report it and move on and don't even worry about what happens, just go on with your life

You can report but it does not guarantee that she will be put in removal proceeding. USCIS looks at the evidences, nothing much you can do now.

Forgive, Forget and Move On...
