Foreign nationals applying for British citizenship on the Isle of Man will have to demonstrate a knowledge of the island and the UK under new rules.
There will be two methods for applying under the new process
People applying for naturalisation will also still have to prove knowledge of the English language.
The Manx government said it was in line with a new process for gaining British citizenship introduced in the UK.
The co-ordinated approach, effective from 1 May, also involves Jersey and Guernsey, other Crown Dependencies.
The special requirements are being introduced on the islands in recognition of their separate identities.
Karen Scott, head of the Isle of Man Government's Crown and External Relations Division, said: "This new process will ensure that people who apply for British citizenship in the Isle of Man will have some understanding of distinctive features of the island."
There will be two methods for applicants to demonstrate that the requirements have been met.
Applicants will be able to take a test based on information contained in a Home Office handbook and in a separate Isle of Man supplement, which is currently being produced.
The supplement will provide a short history and geography of the Isle of Man and cover such topics as to how the island is governed, its legal system and other facets of life.
The test will be administered by the Isle of Man College under normal examination conditions.
The second method is for applicants to attend a language and citizenship course at the college.
