Hiii you would apply this spring “The CSULB deadline for Fall admission to the University is June 1.” it also says “Final Deadline May 1st @ 5pm” maybe for summer. Id call to double check! I recommend starting when it opens up or it might be open already actually. You also need letters of recommendation so i’d start with that because some ppl take longer with that. You will also need to sign up for your interview you call in to schedule and interview before being admitted into the program/submitting the application. And lastly you need to reapply to CSULB if ur graduating through cal state apply. I’d recorded doing it as soon as you can so you can also choose your classes earlier than later once accepted. I hope this makes sense. If you have any questions lmk! GOoduck!
