pretty much depends on what u said to police duriing the investigation . court takes that as a primary source of evidence . if you have minor judge will take soft cornar on that issue . this is a common issue in immigrants like us . you are not screwed, but sinc she was under arrest it will be on public record n can cause immigration issues . the best is to hire a good lawyer who has expertise in this . never rely on online forum . dnt hesitate to hire good lawyer . better safe than sorry . my advise to her would be never leave the country until u r a us citizen .
