How long will kinship take?

How long once a family member is identified will kinship take place? FS parents are to go to court within the next week. Caseworker is going to suggest that FS stay in placement a bit longer as mom is the only one working the plan. She has told cw that she is not with husband at the moment. A family member has come forward and would like to care for fs. We would like him to go to the family member asap as we are growing very attached to him and can see that RU is just a matter of time. CW tells me that kinship takes time and tons of paper work. I am fearful that CW will not do the paper work as she is hoping RU will be within the next 3-6 months. We do not want FS to go to a new foster home but we are at the point where we want to bow out to family if that is where he is going to go eventually. We also feel that mom will not stay heathy long and it would be great if family were ready and waiting. We have always been upfront that we are a foster to adopt home. So just what is involved in kinship? Will the realitives have to take classes as though they are becoming foster parents?
