The competition is open to first generation migrants living in the UK.
This is a sometimes fluid category. Some definitions may include those who:
do not hold a British passport but reside primarily in the UK
have moved to the UK after spending formative years abroad
have moved to the UK as a child, are culturally British but are sometimes seen as a migrant or sees themselves as a migrant
weren’t born in the UK and have English as a second language
are an asylum seeker, a refugee or undocumented in the UK.
Ultimately, you are the best judge of whether you identify as a migrant.
There is no age limit, and no minimum or maximum level of experience to enter.
