<p>2. Continuous residence. The alien must have continuous residence in the U.S.    for at least five years before filing for naturalization. Continuous residence    does not mean actual physical presence and brief absenses may be allowed, however,    a thorough discussion of this issue is beyond the scope of this guide.</p>
<p>The continuous residence requirement for spouses of U.S. citizens is three    years.</p>
<p>3. Residence in state. The alien must have resided at least 3 months in the    state in which the application for naturalization is filed.</p>
<p>4. Physical Presence. The alien must have been physically present in the U.S.    for an aggregate total of one half of the period required for continuous residence,    2 1/2 years for most aliens and 1 1/2 years for spouses of U.S. citizens.</p>
