1. Overview

You might need to apply for a registration certificate to be allowed to work in the UK.

The type of registration certificate you might need will depend on:

  • whether you need permission to work in the UK
  • what you’ll be doing

You must be working, self-employed, studying, or able to support yourself to stay in the UK longer than 3 months.

You can apply for a purple registration certificate before you come to the UK.

You can apply for a blue registration certificate if you don’t need a purple certificate or any other documents to work in the UK.

The blue certificate isn’t essential, but it’s useful because employers will know you don’t need to show them any additional documents to prove that you can work in the UK.

You might still need to show employers your passport or identity card to prove that you’re Croatian.
