Hi, i have a question regarding my friend status. She came to US from India as on dependent visa and her husband has H1b.

Unfortunately there are not many options. She can get a visitor status for a couple of months, but then she would have to go on her own, student/H-1B or other status.

Yes, she can. This is what Violence Against Women Act, or "VAWA" was designed for. Here is a brief description, but you should have your friend contact and attorney to help her file. Normally, if you are a spouse, child or parent of a US citizen (USC) or a spouse or child of a legal permanent resident (LPR) and you want to obtain lawful permanent resident status (commonly referred to as having a “green card”), the USC or LPR has to file a petition with the United States Citizenship and Immigration Service (USCIS) and may need to go with you to an interview with Immigration authorities. Also, if your marriage is less than two years old when you obtain your LPR status, you would normally get what is called “conditional permanent residence,” (commonly known as a “conditional green card”). Your spouse would then normally need to file a joint petition with you to remove the “condition” so that you can obtain full lawful permanent residence. However, in relationships of domestic violence, these requirements for the USC or LPR’s participation are often used by an abuser as a form of abuse, gaining power and control over the immigration status of the victim. Therefore, US immigration law allows certain noncitizen victims of abuse to get legal status on their own without involving the abuser to file anything for the victim. If she is getting a divorce, she should be sure to file for VAWA relief within 2 years of her divorce becoming final, or she will not be able to apply. Sorry to hear of her troubles and I wish you the best of luck.
