I am trying for getting a visa for my parents and younger sister who is 21 years of age. She is doing her masters in India and my father is also working in India. Even if they come they can come for only a month. Would it be advisable to send my parents and my sister together for visa interview. My concern is since my sis is young are the chances of rejection high? Will she going with my parents affect their probability of getting a visa too ?
Really appreciate any information in this regard.
