Visa interview is a face-to-face interaction between two individuals. No matter the level of financial security and educational background backs up for you, preparation is a must. Know the program and how it fits you – The more you know about your program, the more focused your answers will be. You should be able to prove yourself that you have enough skills, background, and ability to advance your studies or work in the United States. Successful visa interviews are not just based on documentation and background. Personality, enthusiasm, confidence, positive outlook, appearance, and clear communication count heavily in a visa interview.
