ur aunt will enter US, but might be given court date to prove why she stayed in Nepal for so long. Tell her to bring some documentation with her to prove why she stayed in Nepal for that long. This is not dead end. Euta na euta bato huncha yesto kura ma. Kurai sakiyo bhanna mildaina. I am saying this because I have seen one person returning after 4 years, and got the court date asking to prove why he stayed in Nepal for so long. He went back to Nepal for good, because he thought his family needed him more and couldnt stay apart from them again, still I get his immigration letter once in a while regarding the GC so they can fix the court date. Pauna pani time lagcha, gumauna pani time lagcha..maile dekhe anusar..and I am also not a lawyer. :)
