I have told you earlier and i'm telling you one more time; don't worry about your green card. You can keep it. get some bruses, call the cops, make a charge, get a no tracepassing or restriction order and go find a lawer who will file a case for you. You can just go yourself to the Ins office and file some forms. I have read some articles about some women organizations helping foreign girls in special cases like these. Do not worry and call the cops asap.... where are all the US graduate feminist ladies who brag about their education here. It's time to help your sister out. Or shut your pie hole braging about feminism, for once and ever if you gonna keep your peace on this case where a Nepali women is being a victim.
