I am living in USA with H1B VISA. My parents are in India. We ave applied B2 VISA for my parents and scheduled Interview. However my mother is not educated and my father is went to only high school. For them the names of cities, employers are worked are very new and they can not pronounce properly. And they don’t know all the visa related process and stuff also not proper. And also they use more dialects, slang and words which is very local to our native place and not a kind of text book language.
At this situation, I am little skeptical about their success in the VISA interview. How can I best prepare them for the VISA interview and what are the best tips and advices that I can give them?
