Can you keep your Lesotho citizenship when you become a U.S. citizen?
Allowed
Yes, in general
Basotho citizens who become U.S. citizens generally keep their Lesotho citizenship, since dual nationality was allowed by a 2018 constitutional amendment.
What the law says
- Dual nationality was typically not allowed in Lesotho, except in cases of automatic acquisition through marriage.
- A 2005 High Court decision ruled nationals of origin could not be deprived of Basotho status if they acquired another nationality for economic reasons without intending to terminate domicile or residence.
- A conflicting 2008 Court of Appeal ruling held voluntary acquisition of another nationality could be grounds for denaturalisation.
- In 2018, the Constitution was amended to allow dual nationality.
- Basotho nationals can renounce their nationality pending state approval.
“In 2018, the Constitution was amended to allow dual nationality.”
What about the U.S. side?
The United States allows dual citizenship. At the oath ceremony you promise to renounce allegiance to other countries, but U.S. law does not make you formally give up your other passport. The question is only whether Lesotho lets you keep yours.
