My kids have the chance to apply for dual nationality, the second country (other than the UK) being an EU country where a grandparent was born.
I can see that doing this might be really useful in giving them the chance to live, work and study in the EU.
Just wondering if there are any downsides or potential problems that we need to consider? They don't have to pay tax unless they live in the country for more than 50% of the time.
