Spanish nationality denounce citizenship. Technical formality?

@linsaywv I have been through it in reverse. I am Spanish and became British as well. I did not lose the Spanish nationality. In your case the Spanish authorities may ask for you to declare your intention to lose your US nationality but such declaration will have no effect for the US authorities unless you tell them directly that you want to stop being American. I even doubt the Spanish authorities will process such declaration. In any case you need to make clear to the US want to remain their citizen. read here: https://echeverriaabogados.com/es/blog/ … dad-origen

I went through it. Seemed like a total formality. There is a line when I signed the citizenship papers that was something along the lines of I denounce any previous citizenships, but the USA doesn't see it that way. The USA immigration website even has a statement on this topic. If you wanted to actually denounce your USA citizenship you would have to complete a formal process and pay a few like you are saying. Just a formality

Hi thanks for that. So when you signed that line on the application that you are to  give up your previous citizenships, that information isn't relayed to your country of citizenship?  Seems that it's a more involved process for instance to denounce your Canadian or your present US citizenship. And that signing the part of the application where you give a previous citizenships would have no effect whatsoever am I correct in presuming that?

@Carlosan71  Thanks, that makes sense. I looked at the Canadian process to denounce your citizenship and one must fill out several forms and pay a small fee so I can see that just signing something out an embassy wouldn't really have any repercussions and it is in fact kind of a formality.

Correct, from my understanding and what I was told there is no agreement between Spain and the USA to share this information. In Spain you are Spanish and in the USA you are American. Everywhere in between is up to you to make sure you understand the legalities and what is best for you.

Upon obtaining my first Irish passport in 2010 I have not renewed my British passport.

i have a legal background in U.K.

i could make a legal argument that having

not renewed my British passport and having

bo intention to do so, I have in effect ‘renounced' my British nationality.

Most people who obtain Spanish nationality, who because of their status, are required to renounce their former nationality, do not make a formal application to do so.  Unless they were discovered with two passports they would not have any problem

A lawyerly opinion follows:

"If I acquire Spanish nationality by residence, do I lose my nationality of origin?"

Their interpretation is that Spain does not allow dual citizenship (for non-Ibero-Americans), but that enforcement of such a restriction is weak.

In particular, they differentiate between "renunciation" and "declaration". The former is a formal act that you undertake according to the laws of your current country of citizenship, and which has the effect of losing your citizenship (and the passport that goes with it). The latter is part of the process of acquiring Spanish citizenship, whereby you "say" that you "renounce" your previous citizenship.

You say this in a sworn declaration, the "Nationality Oath" or "la Jura de Nacionalidad Espanola". In this you promise "loyalty" to the King and "obedience" to the Spanish Constitution and its laws... and you "renounce" your previous citizenship.

The key point is that "saying" it in Spain doesn't (necessarily) "make it so" (in UK, USA, or wherever you're a citizen).
