If you are over 18 you have the right to decide who you associate with. However, if you are living in a foster home or with a relative they may still set limits on who can come to their home. These, “rules,” should be discussed and agreed upon with your caregiver when you move in.
If you are under 18, you have the right to participate in extra circular activities and go to friend’s houses, and talk to them on the phone. However, your foster parent has the right to limit your ability to do these things if they think it would be unsafe or illegal for you to do so. Talk with your social worker if you feel that you are being unfairly limited in what you can do.
