Is it a formal admission notice to receive the admission email from the dean of ucla School of Architecture?

Generally, your personal information will be sent to the US Immigration Bureau at the same time when the school sends out the admission notice email, and you will declare to the Immigration Bureau to obtain your I-20 form. If the process is fast, it will take several days, and if it is slow, it will not exceed one month. The school will send you the printed paper version of the admission notice, together with school profile, accommodation plan, dining plan and other documents and your I-20 form by email.
