Divorce for harrasement from wife

Hi, i am a indian muslim living in US by doing MS and later getting a job, since 9 yrs , i recently got married on 11 dec 2016 to a poor muslim girl without taking any dowry. Post 2months of our marriage i took my wife to US on H4 visa. From the very 2nd day of coming to US she made my life hell by suspecting me for having an affair with my friends there. She is extremely possesive, creates huge scene and arguements for silliest of issues, black mails and threats me that she will commit sucide ( i have videos where she admits to it) When finally i got tiered with her behaviour asked her to go to india for 2 months so that we can sort out our difference in the presence of families and may be come back with my mom after ramzan, for this ran on the roads threating to die which caused a scene infront of the cops there. luckly they asked us to solve issues at home. Some how i sent her to india. Then i came recently now i want a divorce without having trouble to my visa and any cases hopefully. She will never agree for a mutual divorce, what are my options how can i get help. Please suggest.
