Can you keep your Ecuador citizenship when you become a U.S. citizen?
Allowed
Yes, in general
Ecuadorian citizens who become U.S. citizens keep their Ecuadorian citizenship, since nationality can only be lost by voluntary renunciation.
What the law says
- The 2009 Constitution states that Ecuadorian nationality can only be lost by voluntary renunciation.
- In 1995, Ecuador unilaterally allowed dual citizenship.
- In 1998 the legislature modified the constitution to completely remove exceptions for discrepancies between nationality requirements.
- Dual nationality in Ecuador was first introduced in the Constitution of 1995.
- A 1964 treaty with Spain recognized dual nationality between the two countries.
“Ecuadorian nationality can only be lost by voluntary renunciation”
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 Ecuador lets you keep yours.
