US Tourist Visa B2 Extenstion

[sincanvin]

Hi,

My sister in law is 20 yrs old & has little retarded intelligence. She went for US tourist B2 visa interview with my in-laws last year and got the visa just for 1 yr. However, my in-laws got for 10 years. We are planning to get them to US next year for tourism. So, if some once could please answer the following questions and help

1. What is the renewal process for her B2 visa?
2. Can some one escort her for the visa interview process as she needs some assistance to answer all the questions.

Thanks in advance for all your help.
