Due to recent "Reasons" my UK passport is not as useful as it once was for traveling, living and working in the EU. However my grandfather is Polish. Which means I am able to get a Polish passport (Citizenship).
I want to do a quick check to see if there would be any downsides to this. (I will do a proper due diligence closer to the time)
I am particularly concerned if there my be National Service or Tax implications. Not just for myself but also for any children I may have. (I/They are/would be currently UK/NZ citizens and NZ tax residents)
So my question is:
Are there any significant downsides to getting a Polish passport, as a citizen of a different country?
