Renewing your visa is similar to how you first applied for your visa. You will need to be able to prove that you can support yourself, and that you are a serious student. The U.S. Department of State may allow you to renew your visa without requiring an interview, but be prepared for an additional interview just in case. Stay calm, answer the questions that they ask, and have the documents below to be able to support your answers to the visa officer's questions.
