1. Visit the Next Steps Center. The Next Steps Center is your portal to all things enrollment.In addition to your admission letter, the Form I-20 is needed to begin the student visa process. You will receive the physical letter a few weeks afterwards. The same will be the case for any merit awards. According to prepscholar, Arizona State has rolling admissions. The turnaround time can be very quick, as in days for sure. I applied to ASU about a week ago and found on that on the ASU portal it said "congrats you're admitted". However, I have gotten no acceptance letter yet. After being admitted to Arizona State University as a graduate student, you can complete your next steps before classes begin.
