In the naturalization process, after passing the English and civics tests, you can be approved immediately or may have to wait months, or even years, before a final decision. On U.S. Citizenship cases, USCIS has 120 days from the date of the interview to render a decision; when USCIS fails to do so, the law allows an applicant to seek judicial intervention by filing a 8 U.S.C. Β§ 1447(b) lawsuit in Federal District Court. This action is also called βWrit of Mandamusβ.
