I have been accepted to a US university and they mentioned I will need an F-1 visa. I want to understand not just how to get it but how to keep my status valid throughout my studies. What are the most important rules?
What is the F-1 student visa and what are the rules I must follow to maintain status?

The F-1 nonimmigrant visa permits full-time academic study at SEVP-certified US institutions. Maintaining status requires: (1) enrolling full-time every semester (minimum 12 credit hours for undergraduates, 9 for graduates), (2) making normal academic progress toward your degree, (3) reporting address changes within 10 days to your Designated School Official (DSO), (4) not engaging in unauthorized employment, and (5) maintaining a valid passport. Your I-20 document issued by your school is the legal basis of your status — treat it as carefully as your passport. Status violations are serious and can result in accrual of unlawful presence.
Key rules checklist for F-1 status maintenance:
The one thing nobody told me before arriving: your F-1 visa stamp can expire while you are still legally in the US studying. The visa stamp is just for entry — your actual status is the I-20 and D/S (duration of status) on your I-94. I panicked when I saw my visa expired after my first year, thinking I was out of status. I was not. But I needed a new visa stamp to re-enter after any international travel. My DSO should have explained this on day one. Talk to your international students office constantly — they are your lifeline.
Something worth understanding that many students do not: the F-1 status is surprisingly fragile. Dropping below full-time enrollment — even for one semester without prior DSO authorization — can technically trigger unlawful presence accumulation. USCIS hardened its interpretation of this in recent years. The pandemic-era flexibilities for online classes are no longer broadly in effect. Some students at pressure-heavy programs get academic difficulties and silently drop courses — please talk to your DSO before doing this, not after. There are authorized reduced course load options for documented medical or academic reasons that protect your status.
