Hello,

Here's a suggested introduction for your F1 visa interview:

"Good morning/afternoon, officer. My name is Venkatesh, but I prefer to go by Venky. I'm from Addanki, India. I'm excited to pursue [Degree Level, e.g., Bachelor's or Master's] in [Field of Study] at [University Name] in the United States. I'm here today to discuss my application for an F1 student visa and answer any questions you may have."

Be confident, smile, and make eye contact. Good luck!
