yes, you also have to to sumbit your resident status to UCLA for tuition purpose. If you want to find the adress, you log onto my UCLA, click on enroll URSA, the click on review SIR, there u should find the residency document requirment.
if you just need the adress :
Staple the requested information to this cover sheet and mail to
Attn: Residence Deputies
UCLA Registrar's Office
1113 Murphy Hall
Los Angeles CA 90095-1429
But I highly recomment that you call UCLA, because they said that I should send copy of my and my parent green cards within 10 business day since the day you submit you SIR. And you should log onto the residency status page to get the form also, not just send your copies of green cards.
