I am currently studing in US and my sister is trying for US too. But the consultantcy people in nepal told her that there is less chance for the visa coz i m here and if she does not show that i m here.Her visa is 100% rejected. so i`m kind of confused.Is the visa chance very low for people who have brothers and sister in states? will the people in embassy know if she tells them that she is the single child? What should i suggest her? please let me know.
