Whether you have moved to the United States to pursue your dream or you want to move closer to family, there are several methods you can use to gain permanent resident status in the country. According to U.S. Citizenship and Immigration Services, you may go through the adjustment of status process if you are already in the United States. Consular processing must be used if you are currently located outside the country. Before you can apply, however, you must determine if you qualify under one of the green card eligibility categories.
