An outdoor advertising campaign will span 6,000 separate sites throughout the UK followed by a television, radio and social media push to coincide with the formal launch of the programme on 30 March.
The £3.75m campaign includes online guidance translated in all EEA languages and is being supported by a significant recruitment drive to bring staff levels to over 1,500.
Immigration minister Caroline Nokes said: “It is my priority to make sure that EU citizens, who have built their lives here and who have contributed so much to our society, continue to feel welcome in the UK.
“That is why I am launching this UK wide campaign, which will include billboards and radio advertising so that everyone who is eligible knows how to apply and gets the status they need.
“I want EU citizens to stay and to continue to call the UK their home and I would encourage all EU citizens to apply once the scheme goes live.”
EU citizens have until at least 31 December 2020 to register online in order to protect their existing residency rights with nearly 200,000 having done so already since testing began.
The government has previously issued a series of radio ads preparing Britons for the impact of a no-deal Brexit.
