The party is proposing to fine transport firms £10,000 per passenger that is illegally entering Northern.
MP Danny Kruger has said that the aim is to stop dangerous criminals from entering the UK through the Northern Ireland border as a backdoor route. However he says that it will not be a border check.
The party have said that they will hire immigration officers to preform checks on busses and trains crossing the border.
The money collected from the fines will be used to fund deportations and other border enforcement.
The party has said they will be asking the Irish goverment to share more information regarding illegal immigrants with the British Home Office as well as introduce measures to stop people who are not Irish or British citizens from boarding public transport heading to Northern Ireland.
