Renew My VisaOn this page:
The U.S. visa application process is the same whether you are applying for the first time or renewing your visa. It is important to know that your visa may still be valid even though the passport it is in expired. The U.S. Embassy cannot transfer your visa from one passport to another. You can travel to the United States with your old passport containing a valid visa, but will need to carry your new, valid passport. Please note that the biodata (name, date of birth etc.) in the new passport should match the old passport and valid visa.
