Q: How do I prove my right to work in the UK?

We must now have checks in place to prove you have the right to work in the United Kingdom, even if you are a UK citizen.

The Home Office Right to Work Checklist identifies numerous documents from three lists as being acceptable proof – but if the aforementioned John Smith (or indeed Vladimir) is a UK citizen then you just need to see and keep a copy of their passport or Birth certificate – that's pretty much it for UK citizens.

If the individual has been granted the right to live and work here under the EUSS he will have a "share code" that you can use for confirmation.
