One of hardest and most expensive visas to get is the U.S. Visa.  It costs a lot of money to apply and it takes up a lot of your time too.

The visa interview has personal and consequently unpredictable factors involved whether your application gets accepted or rejected. I'm sure no one will ever wish to get rejected.

Consular officers would not want you to stay illegally in the U.S. Even though the country is a place of immigrants, it does not mean that anyone can enter to U.S. for any reason. They would really like to see that applicants are honest, stay for the authorized duration and come back promptly after that.

Following these tips will not guarantee a passing interview but it will surely help you in a lot of ways:

PREPARE ALL THE DOCUMENTS. Have your documents ready just to be on the safe side. Sometimes, the interview officers only ask questions and do not require the interviewee to show any of his documents.

DRESS YOUR PART. The interviewing officer will always be an American. If possible, a man should wear a tie. If your documents state you're an employee, then wear something corporate. Americans appreciate formal attire so they will not find you over-dressed. Pick your outfit that makes you look like what's indicated in your documents.

ARRIVE EARLY. The lines are long.  Arrive at least 30-minute earlier the given interview time. You don't want to miss your interview just because you got stuck in traffic.

BE CONFIDENT. Don't show signs of nervousness. Being able to speak English properly is a major plus. All you need is your confidence when answering and smile when you meet the visa officer for the first time.

ALWAYS REPLY WITH CORRECT ANSWERS. If your visa is rejected once, you can't be changing your details the next time you go for an interview. All data while applying for the visa and details of the answers given in your interview are computerized and maintained.

BE POLITE. Do not unnecessarily elaborate your responses as this may not work in your favor. Do not argue and do not ask unrelated or unnecessary questions.

Always remember, if you don't get the visa, it doesn't change anything in life and that's not the end of the world. We always have another chance.
