Visitor Visa extension - second time (but after long)

[Haryana]

Hi,

My mother came to US in Nov 2007 and she went to India in Sep 2008 though her extension was till Oct 2008.
Then she came back in May 2010 and stayed till Oct 2010 (Went back after original I 94 expiry in Oct 2010).
This time she came back in Sep 2012 (after 2 years).

We are planning to extend the I94 for 5 months now, what are the chances of extension. She has stayed more time in India than in USA.

Thanks

Chances are anybody's guess. But remember that with repeated extension she will hamper her chances of getting a Visa renewal.
