After the Referendum that took place on the 23th of July 2016, resulting in the exit of the UK from the European Union, the current conditions of the Au Pair Program will not change. The final exit process between the UK and the EU has a time period of 2 to 5 years, depending on the negotiations between the European Union Council and the British Parliament.
As such, the current conditions of the Au Pair Program in the UK will stay the same, as such will the conditions regarding the rest of the countries in Europe.
To remind you of the current conditions of the Au Pair Program in the UK:
Citizens of the European Union or EFTA do not need any visa to be an Au Pair in the United Kingdom. They only need a valid passport, and an agreement executed with the family.
Australia, Canada, South Korea, Hong Kong, Japan, New Zealand, and Taiwan have a Youth Mobility “Tier 5” agreement with the United Kingdom, by means of which citizens from said countries may request this type of visa for a maximum period of two years.
To that effect, they must contact the embassy of the United Kingdom in their country in order to check requirements, expected number of visas they will need for a year and necessary information to file their request. To obtain such visa, factors such as age, nationality, and financial resources are taken into consideration.
Any Au Pairs not included in the foregoing list will need to request a student visa for the United Kingdom. To that effect, they will need to comply with a series of requirements imposed by the government of the United Kingdom and on which you may get information in the UK embassy in your country or in the essential links section below.
