There are many different types of American visas, each with its own specific requirements and fees. In order to visit the United States, you will need to apply for the correct visa depending on your purpose of travel.
Who can apply for American Visa?
To be eligible for an American visa, you must first meet the general requirements which include having a passport that is valid for at least six months from the date of your planned departure from the US, a recent passport-sized photo, and a completed visa application form.
You will also need to show proof of your purpose of travel, such as a letter of invitation or confirmation if you are visiting for business purposes, or evidence of financial support and accommodation if you are visiting for tourism.
Applying for an American visa can be done online or by post, and you will usually need to attend an interview at the US Embassy or Consulate in your country as part of the process.
