Sorry about the title, but I tried to make it as close to what I had put into Google when I was in this situation. This is kind of a trivial post, but I’ve gotten enough emails about the subject that I thought I might as well write one to resolve future inquiries.
As a lot of UCLA MBA admits including myself have experienced, the process of submitting your SIR (Statement of Intent to Register) and SLR (Statement of Legal Residency) has been somewhat unclear.  While everything you need to complete the process is technically there, the communication between the MBA Admissions and Graduate Division offices hasn’t been totally in sync.
The first place where everyone should start is the MBA admit Master Checklist. Here you’ll see that it clearly states that you’ll receive links to submit the SIR and SLR along with your formal offer letter.
