Life in the United States is something that many people dream of. Although there are visas that allow a person to live and work in the U.S., these are temporary and must be renewed at regular intervals. In order to stay on a long-term basis, an immigrant must obtain a green card. Getting your green card isn't easy. Some people may assume that marrying a citizen is the only way. Fortunately, there are other ways to qualify for your green card.
