The visa application cost is also determined by the nation to which you seek to immigrate. The application cost for the most prevalent nonimmigrant visa categories in the United States, for example, is $160. This comprises visas for tourists, business, students, and exchange students.

A student visa is not difficult to avail. However, if you have a student visa, it only allows you to enter a country to study and nothing else. If you have completed your study, you cannot live in a country on a student visa.

Applying for a tourist visa is very easy. First of all, you need to fill out the form for a tourist visa online. For this, you can go to the official site of the country's embassy. After applying you will have to pay the fees and complete an interview with the embassy.
