Can an American living in the UK become a British citizen without losing American citizenship?
<p>If an American citizen living in the United Kingdom (England if it matters) meets all of the <a href="https://www.gov.uk/british-citizenship" rel="noreferrer">UK's requirements for naturalization</a>, can he become a British citizen without losing his American citizenship?</p>

<p><strong>Yes</strong></p>
<p>From the American perspective:</p>
<blockquote>
<p>U.S. law does not mention dual nationality<sup>1</sup> or require a person to choose one nationality or another. A U.S. citizen may naturalize in a foreign state without any risk to his or her U.S. citizenship. <em>Source</em>: <a href="https://travel.state.gov/content/travel/en/legal/travel-legal-considerations/Advice-about-Possible-Loss-of-US-Nationality-Dual-Nationality/Dual-Nationality.html" rel="noreferrer">U.S. Department of State — Bureau of Consular Affairs</a></p>
</blockquote>
<p>And from the British:</p>
<blockquote>
<p>Dual citizenship (also known as dual nationality) is allowed in the UK. This means you can be a British citizen and also a citizen of other countries. <em>Source</em>: <a href="https://www.gov.uk/dual-citizenship" rel="noreferrer">Gov.Uk</a></p>

<hr />
<blockquote>
<p><sup>1</sup>Section 101(a)(22) of the Immigration and Nationality Act (INA) states that “the term ‘national of the United States’ means (A) a citizen of the United States, or (B) a person who, though not a citizen of the United States, owes permanent allegiance to the United States.” Therefore, U.S. citizens are also U.S. nationals. Non-citizen nationality status refers only individuals who were born either in American Samoa or on Swains Island to parents who are not citizens of the United States [<em>Source: Dept of State, as above</em>]</p>
