Several requirements must be met to obtain U.S. citizenship through naturalization after obtaining a green card. These include being physically present in the U.S. for at least 50% of the time as a green card holder, not being absent from the U.S. for more than one year, and having no serious convictions for crimes of moral turpitude. In addition, one must be able to read, write and speak English. It is recommended to seek the assistance of an immigration attorney to obtain a complete list of requirements and qualifications.
