So I'm a dual citizen. One is an EU country so it’s under the VWP, and the other is not. I have a valid us tourist visa on the non-EU passport but it's about to expire and at the time. Because of the country's situation is very hard to renew the passport.
So my question is if I have a valid visa on an expired passport without being able to renew it, should I just simply apply and use the ESTA on the EU passport and disregard the visa on the other.
P.S. - I’ve heard that if you have a valid visa you shouldn’t even apply for the ESTA and I know people that have been troubled during immigration because of this.
