25 Guernsey firms will be alongside the Locate Guernsey team to promote the benefits of a move to the Bailiwick.
Locate Guernsey will be in St Paul's Cathedral on 9 October.
Seminars, networking sessions, and exhibitor stands will outline the Guernsey lifestyle, property market, education system, healthcare and business environment.
Locate's Gill Mabbett, says the event has grown threefold in three years, with around 600 guests expected.
“We’re proud to be showcasing the depth of expertise and collaboration that exists within our island.
"Attendees will have the chance to speak directly with professionals who understand both the opportunities and realities of relocating to Guernsey.”
She says Guernsey has many attractive qualities.
"We have a low crime rate, there’s no commute, and there is freedom for children.
"We don’t have a fast food culture, we have Sark, Alderney and Herm to enjoy, and St Peter Port has kept its charm.
"I am originally from Scotland, so I always talk about the weather and it's just that little bit sunnier."
Gill says they don't avoid highlighting the challenges that come with island life.
"We talk about if you are going to catch a long-haul flight, sometimes you should fly to London the day before.
"So yes, it is important for us to manage expectations about moving to the island, but also the benefits outweigh the negatives - you are buying into a lifestyle."
