A visa is a type of authorization or a legal document which is given by the country to the foreigner so that they can stay in that country either permanently or locally. The visa is granted for a particular span of time. Different types of visa are granted to foreigners on the basis of time-period to stay in that particular country.
There is a special visa for the businessman who wants to work in USA which is known as business visa USA E2. It is a type of non-immigrant visa which allows the immigrants to work in the USA without becoming the permanent residents of that particular country.
This visa can also be issued to entrepreneurs of that country with which the USA has a treaty of trade and commerce. This business requires a substantial amount of investment. E2 visa holders may stay outside the USA for a certain amount of time and can still re-enter the USA. It is renewed after every two years. The main advantage of e2 investor visa is that there is no minimum investment required.
Although if the business fails, the person who is granted this visa has to leave USA without visa getting expired. This enables to enhance the overall economy of the country.
