Visitor Visa for my sister

[Nayaki]

Hi, I am on L2 and my sister is planning to visit me for 3 months.

She is sponsoring herself. Is there any documents that I may need to send to her? Or will her financial papers suffice?

Further ties: She is employed as partner in an accounting firm and has a daughter going to school.

What are her chances of getting the visa? Pls guide.

Nayaki,
Her chances will depend on several variables. Her citizenship. Her ties to her country of residence. The consulate. Even the consul's mood that day. By law the interviewing consul will assume that she is an intending immigrant. The burden of proof is on your sister to prove otherwise.
Good luck to her.
