How soon after relocating is it possible to file a lawsuit in a federal district court?
<p>In the US, if I relocate from one judicial district to another judicial district in another state — how soon after relocating is it possible to file a lawsuit in a federal district court?</p>
<p>(I plan to sue the federal government over a citizenship application being processed beyond the time frame set by the federal law)</p>

<p>You mention</p>
<blockquote>
<p>Several immigration lawyers in the US told me that I have to sue in the district where I reside.</p>
</blockquote>
<p>And you ask</p>
<blockquote>
<p>how soon after relocating is it possible to file a lawsuit in a federal district court?</p>
</blockquote>
<p>You can sue as soon as you can credibly assert that you reside in the new district.  If you live in a camper van, this might be somewhat more difficult to establish, but that is probably a topic for a separate question.</p>
<p>However, in order to be naturalized, you must meet the requirements in <a href="https://www.law.cornell.edu/uscode/text/8/1427" rel="nofollow noreferrer">8 USC 1427</a>, which says in part that the applicant must have resided</p>
<blockquote>
<p>within the State or within the district of the Service in the United States in which the applicant filed the application for at least three months.</p>
</blockquote>
<p>This implies that if you move to another state and another USCIS district after submitting your application that you must file another application (there may be a provision for this case that allows you to move after applying, but if so, I haven't found it).</p>
