The 'Full Course of Study' Rule
One of the most fundamental requirements of the F-1 visa is that you must be enrolled in a 'full course of study'. This isn't just about showing up for classes; it's a specific requirement defined by immigration regulations. For undergraduate students,
this typically means at least 12 credit hours per semester. For graduate students, the requirement is set by your institution. Falling below this course load without prior authorization from your Designated School Official (DSO) is a serious violation. Your DSO is the key person at your university's international student office who manages your student visa status. Only in very specific, pre-approved circumstances, such as a documented medical issue or specific academic difficulties in your final semester, can you drop below full-time. Simply wanting a lighter workload is not a valid reason and can lead to the termination of your visa status.
Understanding Work Authorization
Working illegally is one of the fastest ways to lose your F-1 status. The rules are strict and absolute. During your first academic year, you generally cannot work off-campus. On-campus employment is usually permitted, but it's limited to 20 hours per week during the academic session. Any work, paid or unpaid, that is not explicitly authorized is considered unauthorized employment. This includes casual babysitting, working at a family friend's store, or any freelance gig. The consequences are severe, potentially leading to deportation and a bar on re-entering the US. Before you even consider any form of employment, you must consult your DSO to understand what is permissible and get the necessary authorization.
CPT and OPT: Authorized Training
There are two main avenues for F-1 students to gain work experience: Curricular Practical Training (CPT) and Optional Practical Training (OPT). CPT is an internship or work experience that is an integral part of your curriculum. It must be required by your degree program or you must receive academic credit for it. Your DSO must authorize CPT before you begin working. OPT, on the other hand, is temporary employment directly related to your major area of study. You are typically eligible for 12 months of OPT per education level. This authorization must be applied for and approved by U.S. Citizenship and Immigration Services (USCIS), a process that can take several months. A key rule to remember is that if you use 12 months or more of full-time CPT, you lose your eligibility for OPT at that same educational level.
SEVIS: Your Digital Immigration Record
The Student and Exchange Visitor Information System (SEVIS) is a government database that tracks your entire lifecycle as an international student. Your SEVIS record is your official immigration file, containing everything from your address and course of study to your employment authorizations. While your DSO is responsible for updating the record, you are responsible for providing them with timely and accurate information. This includes reporting any change of address within 10 days, changes to your name, or changes in your major or program. Failure to keep this information current can be considered a status violation. You should think of your SEVIS record as being just as important as your passport and visa.
Major Rule Changes in 2026
A significant rule change is set to take effect on September 15, 2026, which abolishes the 'Duration of Status' (D/S) system for most new F and J visa holders. Previously, students could stay as long as they maintained their status. The new rule will grant a fixed period of admission, generally tied to the program end date on your Form I-20 but not to exceed four years initially. If your program takes longer, you will need to apply for a formal Extension of Stay with USCIS, a process that is not guaranteed. This makes it even more critical to monitor your program dates and your new I-94 admission record closely. The post-completion grace period to depart the US for those under the new rule will also be shortened from 60 days to 30 days.
