I have recently applied for Dutch nationality through the option procedure as latent Dutch (born to Dutch mother and British father before 1985).
Once it is granted to me (hopefully), I can apply for a Dutch passport and my adult daughters would also be able to use the same option route. Both my daughter are also entitled to Irish passports as their father is Irish and one of them has acquired the Irish passport and has let her British passport expire.
The Dutch process and passport are much more expensive, are there any advantages to a Dutch passport over an Irish one? I would like to ‘pass on’ the Dutch nationality, but I doubt my daughters would bother because of the expense and trouble of maintaining 2 or 3 passports. At present they do not intend to live or work outside the UK.
