Working in the UK as a Croatian national

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

The type of registration certificate you may 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.

Working for someone else (an employee)
You may need to apply for a purple registration certificate to be able to work. A licensed UK employer must sponsor you first.

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 is useful so that employers know you don’t need to show them any additional documents to prove that you can work in the UK.

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

If you have a degree from a UK institution

You don’t need to be sponsored or have a purple registration certificate – but you still need to apply for a blue registration certificate to prove your right to work in the UK.

You need to be in the UK to apply.

If you have an endorsement from an approved organisation

You don’t need to be sponsored or apply for a purple registration certificate if you have an endorsement from an approved organisation, eg the Arts Council or Royal Academy.

You still need to apply for a blue registration certificate to prove your right to work in the UK.

Working for yourself (self employed)
You don’t need permission to work for yourself.

You can choose to apply for a yellow registration certificate to prove your right to work for yourself.

You need to be in the UK to apply.

Studying
You need to apply for a yellow registration certificate if you want to work while you study.

You need to be in the UK to apply.

Your family members
Your family members can also work in the UK if they’re eligible.

Purple registration certificate

You should apply for a purple certificate if you want to work for an employer in the UK and can’t get a blue certificate.

You need to be sponsored by an employer first – they’ll give you a certificate of sponsorship number which you need to provide when you apply.

Check your employer is on the list of registered sponsors for this type of certificate before you apply.

You must get a purple registration certificate before you start your job.

Apply for a blue registration certificate instead if you have a degree from a UK institution – you won’t need to be sponsored.

Eligibility
You must have:

a job offer
a certificate of sponsorship number from your employer
You may need to have a good knowledge of English for some jobs.

You need a letter from your employer instead of a certificate of sponsorship if you’re:

a domestic servant in a private household
the sole representative of an overseas business
a postgraduate doctor or dentist doing a foundation programme
When you won’t need a purple certificate

You don’t have to apply if you:

were working legally in the UK without restrictions on 30 June 2013
got a UK visa or work permit before 1 July 2013 which is still valid
have been working in the UK for a continuous period of 12 months ending on or after 30 June 2013
work for an EU company which doesn’t usually operate in the UK (you’re a ‘posted worker’)
are a permanent UK resident or you have dual nationality including another European Economic Area (EEA) country
are the partner of a British citizen
are the partner, child or dependent relative of an EEA citizen (other than a Croatian) or of a person settled in the UK
are a member of a diplomatic mission in the UK
were granted a blue registration certificate that says you’re highly skilled, eg because you hold a degree
You may want to apply for a blue registration certificate anyway to prove you have the right to work.
