Many people coming to the United States require a visa to enter the country, but often are confused about the different types. To simplify the explaination, there are two (2) types of visas: resident visas (also known as "greencards") and a non-resident visas (also known as temporary visas). While many foreigners would like a greencard, not all qualify. There are different requirements for each type, and in some cases it is best to start with a non-resident visa and work towards attaining a greencard.
