Are you the petitioner or beneficiary? Did you update your address? Did you get the approval notice? Is your priority date current? Is beneficiary here in the United States? If so, legal status or illegal status?
Many questions to answer. You should consult with an immigration attorney near you to proceed.
More information may be needed. Did you ever receive an approval letter? Your visa may be current if it has been that long depending on which category the petition falls under. You may want to take the forms to an immigration attorney to look at.
What classification? I'm going to guess brother/sister.
Your next step should be to talk to an immigration lawyer ... things are quite complicated now days.
