To get a green card, one will most likely have to submit an application with the US Citizenship and Immigration Services. There are many types of a USA greencard for which one can apply. The primary ways to get a green card include applying for a green card through family members who are American residents or citizens, applying for a green card through a job, and applying for a green card as a refugee or as a seeker of asylum.
There are a number of other ways to get a green card, however, including getting a USA greencard through the Diversity Immigration Visa Program, getting a green card for an Armed Forces member, getting a green card for a special immigrant juvenile, and getting a green card as a foreign diplomat.
Applying for any of these types of USA greencard will be a slightly different process, as the application for each is slightly different and has different requirements. For example, to get a green card through a family member with a spouse holding US residency being the family member in question, an individual would have to be able to provide concrete legal documentation of the marriage, and would still only get a conditional USA greencard, instead of a full USA greencard.
The different applications for obtaining a USA greencard are all available on the website for the US Citizenship and Immigration Services. To get a green card, an individual must select and fill out the proper application, and must then submit or file that application with the proper authorities. An application to get a green card may also be submitted online in some instances.
