ESTA still valid - obtained dual citizenship in the meantime

Hi folks, I wonder if anyone would know answer to this small issue. I used to travel to US on ESTA nearly every year since 2009 (except covid times) on my birth country (EU passport) with no problems whatsoever. I have currently valid ESTA on that passport until 2025. I have recently gained another EU country citizenship (also eligible for ESTA), I still have valid original passport with ESTA and I retain the original citizenship (dual citizen now). Can I still travel on that original passport without applying for the new ESTA (until ESTA is expired)? I tried to find online on ESTA website and this is what I see in FAQ:

What if I have dual citizenship and/or have a passport from more than one country?

Each Visa Waiver Program traveler must have an approved travel authorization for the passport they plan to use before they travel to the United States. If a traveler obtains a new passport, they must submit a new travel authorization application in ESTA using the new passport. A processing fee will be charged for each new application submitted.

If you have dual citizenship and have registered with ESTA, you should use your VWP-eligible passport to board the plane when you leave your country of departure and when you arrive in the U.S. If both your countries of citizenship are VWP-eligible, then we strongly recommend you choose which one you want to claim for purposes of travel to the U.S., and use that country's passport each time you travel. One person with two different ESTA authorizations creates confusion that will only delay your travel.

Not sure whether the text cited comes from an official source but it clearly gives the answer to your query.

You can travel to the US using the EU passport containing the ESTA until its expiration. No need to apply for another ESTA in the new passport.

thanks, just the issue is that at the time I applied for this ESTA, I didn't put into application I'm a dual citizen (because I wasn't at the time) so not sure if I need to reapply because of that change. Yes I still have that passport I travelled to US last time and it's valid, just was thinking if they won't cause me some hassle at the border.

That's not an issue.

Again, you have the answer to your own query.

Nobody can predict the future. You applied for an ESTA with a valid VWP-eligible passport and it remains valid despite you obtaining other nationality(ies) afterwards.

The text cited says that VWP-eligible nationals with dual citizenship only need to choose one passport to register the ESTA to and that's it. You already did so.

You have got akk your concerns correctly addressed by lolo2

I appreciate the answers and will travel on my original WVP until it will expire in april 2025.

Just got confused by this:

When do I need to reapply for an ESTA?
A new travel authorization may be required in any of the following circumstances:

The traveler is issued a new passport
The traveler changes his or her name
The traveler changes his or her sex
The traveler's country of citizenship changes; or
The circumstances underlying the traveler's previous responses to any of the ESTA application questions requiring a "yes" or "no" response have changed.

You acquired additional citizenship not that you renounced the one which you used in getting the ESTA.
So this does not apply in your case.
