UK, Ireland / Help Renouncing UK Citizenship and gaining Polish one [24]

Merged: Getting Polish citizenship

I'm a UK citizen. I'm probably moving to Poland next year. I think I can get EU funds to start a business there .

I want to get Polish citizenship in case the UK exits the EU. I understand it only takes 3 years.
I would be grateful to anyone who has been through the process who can give me some advice.
