This is arguably the most important section in the entire guide. Everything else — your bank account, your apartment, your job prospects, your social life — depends on one thing: maintaining legal F-1 status. Lose it, and none of the rest matters.
The good news is that most visa violations are accidental, not intentional. Students drop a class without realizing it puts them below full-time, or they accept a freelance gig without knowing it counts as unauthorized work. The rules aren't complicated — but you have to know them before you make a decision, not after.
Golden Rules
| Rule | Requirement | If Broken |
|---|---|---|
| Full-Time | Full course every Fall/Spring | SEVIS terminated |
| Credits | Undergrad: 12. Grad: 8–9. | Out of status, even by 1 |
| Online Limit | Only 1 online class (3 credits) | Not considered full-time |
| Progress | Consistent degree progress | DSO review triggered |
Reduced Course Load (RCL)
Sometimes life happens — you get sick, a class is harder than expected, or you're in your final semester with only a few credits left. The system accounts for this. There is a legal process to take fewer classes, but you must get approval before you drop below full-time, not after.
Need a new I-20 with RCL authorization before reducing load:
- Academic Difficulty: First year only
- Medical Reason: U.S. doctor letter required
- Final Semester: Only 1–2 classes left
Address Changes & I-20 Management
Your obligations go beyond just staying enrolled. SEVP (Student and Exchange Visitor Program) requires you to keep your records current at all times. This means reporting any change of address to your DSO within 10 days — not when you get around to it.
- 10-Day Rule: Report address changes within 10 days.
- I-20 never expires on its own: If your program end date is approaching, apply for a Program Extension before it passes.
- Scan every I-20 you receive. Future employers and immigration attorneys will want your full history.
- Create a digital folder (Google Drive or iCloud) for all immigration documents. Scan every I-20, visa stamp, I-94, and correspondence with your DSO.
- Set a calendar reminder 6 months before your program end date to start the extension process.
- Never travel internationally without checking with your DSO first. You need a valid travel signature on your I-20.
