A Green Card application is a big part of the process by which an individual must follow to gain permanent residency within the United States. This application must be filled out sufficiently along with all other criteria that an individual must meet prior to getting their Green card and ultimately gaining permanent residency within the United States. There are a variety of ways that an individual may qualify for a Green Card which include through employment, through a relative, or after living for a consecutive number of years within the United States. Each type of qualification means that there is a different type of application that must be completed to the satisfaction of the government.
