Hi, I am from south east asia (Bangladesh), I am living in Spain with no immigration status (illegally).
I heard that if anyone is a relative of an EU Citizen is eligible for the permanent residence card under
Regimen Comunitario. I have relative such as brother and sister who are UK Citizen.

My question is-

1. Is it possible for me to get permanent residence card under Regimen Comunitario on the basis that I have
British brother and sister? or
2. Do i have to be a spouse of a EU citizen to get permanent residence card under Regimen Comunitario ?

And also if its possible can u please tell me what is the process of application.
Your answer will help me a lot, thanks.

Best Regards,
Siddik
