The actual process of applying for a visitor visa to enter the United States on a temporary basis will vary from country to country.
In some cases you may get your visitor visa to the United States with the help of a sponsor.
When you apply for a visa you will be asked to pay a visa application processing fee. This fee is non-refundable - even if your application is denied you will not get this fee back.
Having to have an interview to get a visitor visa is standard - it is nothing to worry about. This is just one of the ways that the embassy/consulate will check you out to assess whether to give you a visa.
Not every application for a visa will be given the go-ahead. Having a refusal for a visitor visa can be based on many reasons. The most common (section 214(b)) tends to be that the applicant could not show strong enough ties to their home country so the immigration system did not consider their return home a strong enough possibility.
