Even if India can sneak her out, this woman will forever be a fugitive in the eyes of the US law enforcement. She will never be able to set foot outside India again except NK or Cuba.
The US Department of Justice and the NY DA aren't going to drop the charges unless it is for a real good lawful reason. The good reason would have to be acceptable by the US public.
The US law enforcement is VERY good in piling on charges. You see, from a fraudulent visa application initially to human trafficking. Human trafficking is a serious crime, not just in the US but in all civilized countries.
Law rules supreme in the US. Law is above the flag, the president. When the department of justice is involved, the state department is helpless. Even if Kelly wanted to smooth thing over, the DOJ would tell him to jump into the lake.
