The length of a visitor’s initial permission to stay in B-2 status is determined by the officer at the port of entry. The maximum initial period is six months. People who want to remain longer need to apply for an extension.

I want to start my parents visitor visa process. I checked all the documents check list and i had a question on w2.

Do you have any other ideas or documents that are important ?

My mother went for B2 visa interview in Aug 2012 but because of an unfortunate incidence, she was asked to come back after 3 month (a specific date in Nov 2012 was mentioned in her 221(g) blue form. No additional docs were asked for).
