[searea88]

I am a Canadian working in the US with a TN visa. My wife is here on a visiters visa (Russian) with her daughter. Can she extend her stay without leaving the US.

I-539, application to extend/change nonimmigrant visa

this is what the Application to Change/Extend Nonimmigrant Visa is for. submit one each for wife and daughter to nebraska service center. if approved, their visitor's stay is extended. If denied, they are to return home.

Thanks John for your reply. Do you know on what grounds the application could be turned down.
