Can persons holding dual/multiple citizenship obtain multiple social security incomes?
<p>Say a person is citizen of Country A. Person applies for citizenship of other countries B,C,D where Country A's citizens are eligible to apply for dual citizenship. </p>

<p>Person A reaches the age or conditions that make the person eligible for Social Security. Can such a person technically, or by craft obtain Social Security income from multiple nations ? </p>

<ol>
<li>Yes/No ? </li>
<li>If No,what are the general principles of law to regulate misuse/abuse of SS income. Assume jurisdiction US, UK,Canada. US Citizens also hold dual citizenship with Canada, some such persons are also UK citizens.  </li>
</ol>

<p>SS benefits are determined by national policy, and it is difficult to generalize over all jurisdictions. However, in the US, it is <a href="https://www.ssa.gov/ssi/spotlights/spot-non-citizens.htm" rel="nofollow noreferrer">not necessary to be a citizen to collect benefits</a>. You have to qualify (such as working 40 quarters) – thus even being a citizen does not guarantee benefits. Non-citizens are not subject to the same rules as citizens, but one unquestionably can receive benefits. The <a href="https://www.canada.ca/en/services/benefits/publicpensions/cpp/cpp-international/eligibility.html" rel="nofollow noreferrer">qualification rules in Canada</a> are different, but again, you don't have to be a citizen and there are ways to combine qualification years across countries. In the <a href="http://ec.europa.eu/social/main.jsp?catId=849" rel="nofollow noreferrer">Greater EU</a>, people freely move from country to country and accumulate years of pension benefits, without the need to change citizenship.</p>

<p>I am not aware of any country that requires national pension scheme recipients to be citizens.</p>

<p>Logically, countries will be reluctant to pay social security benefits if you haven't been paying them taxes. You can find the relevant agreements for a US citizen here:</p>
