How to get student card?

Excuse me, could you please explain the process of obtaining a student card? I'm new to this institution and I'm not sure where to start. Do I need to fill out any forms or submit any documents? Also, is there a specific deadline by which I need to apply for the student card? And once I have the card, what are the benefits and privileges that come with it? I'd really appreciate it if you could guide me through the entire process step-by-step.
