This is a nonimmigrant visa for a temporary stay for business (B-1), tourism (B-2), or for a combination of both purposes.
You may want to apply for business if you are seeking consulting with business associates; attending a scientific, educational, professional, or business convention or conference; settle an estate or negotiate a contract.
If you consider applying for a tourism visa, you should know that this type of visa also covers medical treatments, participation in social events like music, sports, or any other contests. It is not only for vacation and recreational purposes.
The process of applying may vary by U.S. Embassy or Consulate. Nevertheless, in most of the cases it will consist of completing an online visa application and attending to a schedule interview. If the application is 13 and younger or 80 and older, it might not be required to appear for an interview in the consulate.
The Visa Application is online and wait times for interview may vary by location, season, and visa category.
