Hello, my husband is Dutch and we live in Texas. We have a very good life here. He’s planning on becoming a US citizen once he’s eligible but I’m not sure if we can keep both passports. If not, he said he was going to give up his Dutch citizenship. I was just wondering if there’s any benefits in keeping it (as we have no intention in ever living in Europe and he no longer has family there).

He is allowed to keep it if you are a US citizen, so he is taking the citizenship of his partner (rule 3). However, due to living outside the EU he has to request a new Dutch passport at least once every 13 years (so within 3 years after the old one expired, as passports are valid for 10 years.)
