Bulgarian and Romanian nationals do not need to seek an extension to their initial approval under the work permit arrangements. Once a Bulgarian or Romanian national has been given permission to work under the work permit arrangements, and has obtained an accession worker card, the card will be valid as long as the Bulgarian or Romanian worker remains in the employment for which the card has been issued.

A Bulgarian or Romanian national who has been working with permission and without interruption in the United Kingdom for 12 months may apply for a registration certificate confirming their unrestricted right to access the United Kingdom labour market.
