You may apply for equal status with Danish students and apply for state education grant (SU) if you are an EU, EEA or Swiss citizen, and:
1) You are a worker or self-employed person in Denmark under EU law and will continue to work while studying.
Read more about being a worker or self-employed person under EU-law
2) You have retained your status as a worker under EU law on the basis that you:
have previously been a worker or a self-employed person in Denmark and there is continuity (a connection in terms of time and content) between your work in Denmark and the education programme for which you are seeking SU (e.g. you have worked as a nursery assistant and choose to study to become a nursery teacher immediately afterwards), or
have been a worker or a self-employed person in Denmark, but in need of retraining after becoming involuntarily unemployed due to particular structural conditions on the labour market or for health reasons (e.g. you have worked as a physiotherapist, but have developed rheumatoid arthritis and can no longer work in this role and therefore need to undergo retraining).
Read more about when you meet the conditions for either continuity or retraining.
