Best way to extend/get Visa beyound 6 month? Mother-in-law

[marlon2006]

Hi,

Imagine mother-in-law is senior citizen (70 year). Her US Visa is valid till Nov 2011.

She got visa for 6 months at port of entry in the US.

Is it realistic expect to get extension for her if I apply for extension while she in the US?

Or, sometimes I hear people they go to Canada or Mexico and then come back to US. Is that likely it could work?

Note:
I am professional with greencard applying for citizenship on 08/11/2011.

Yes, provided it is a true emergency that justifies an extension application.

Is it realistic expect to get extension for her if I apply for extension while she in the US?
