If you want to apply for a residence card under EU/EEA rules
Your family member who is a Nordic citizen can also be considered an EU/EEA citizen. You can therefore choose to use EU/EEA rules and apply for a residence card under those rules. In order to do so, your family member must meet the requirements for right of residence through work, running their own company, by studying here, or by living here with sufficient financial means to support themselves.
