Thank you for your reply. I'm an extended family member of one. I'm just worried that after 5 years I may not be able to obtain permanent residency that's why I asked.

I'm living in the UK on a EEA family member resident card/permit. I've got 5 years on my resident card but i was curious to know if upon receiving the 5 year EEA resident card does it mean after the 5 years I'll be guaranteed stay here ?
