F-1 Rules & Work (CPT, OPT, STEM OPT, On-Campus Jobs & Transfers)
Studying in the United States on an F-1 visa comes with important rules and timelines. This page explains the practical side of being an F-1 student—how to maintain status, what work is allowed, how CPT/OPT/STEM OPT work, how transfers happen, and what to avoid. We explain everything in simple language so students can make the right decisions and stay compliant.
A) Maintain Your F-1 Status (Most Important)
To stay in lawful F-1 student status, you must follow the rules set by your school and U.S. immigration requirements.
Key requirements:
Stay enrolled full-time each term (unless your DSO approves a reduced course load).
Attend the school listed on your I-20.
Keep your passport valid and keep your contact details updated.
Follow program dates shown on your I-20.
Do not work without authorization. Unauthorized work is one of the fastest ways to violate status.
Reduced Course Load (RCL):
Sometimes students can take fewer credits (for example, medical reasons or final term). This must be approved by your DSO (international student office) before you drop classes. Never assume it’s allowed without written approval.
If you fall out of status:
You may need a reinstatement or may have to leave the U.S. and return with a new I-20/visa plan. Every case is different, so get guidance early.
B) On-Campus Work (Allowed Without USCIS Application)
On-campus work is the most common legal work option for F-1 students.
What counts as on-campus work?
Jobs located at your school (library, dining, lab assistant, IT desk, etc.)
Some school-affiliated locations if the job is connected to the institution
Typical rules (general guidance):
Allowed during the semester with a hour limit
May allow more hours during official breaks
Must maintain full-time enrollment and good status
Important:
If you start working without being eligible or if the job is not truly “on-campus,” it can become unauthorized work. Always confirm with your DSO.
C) CPT (Curricular Practical Training)
CPT is work authorization for internships/training that are part of your academic program.
What CPT means (simple):
CPT is an internship/work opportunity that is connected to your degree requirements—often tied to an internship course or academic requirement.
Common CPT requirements (varies by school):
Usually available after completing one academic year (some programs allow earlier if required)
Must have a job offer before CPT can be approved
Must be authorized by your DSO on your I-20 before you start working
Often requires enrollment in a related internship course
Part-time vs Full-time CPT:
Part-time CPT is limited hours/week
Full-time CPT is higher hours/week
Your school decides how they define it.
Very important OPT rule:
If you use 12 months of full-time CPT, you may lose eligibility for OPT. This is why CPT strategy matters.
CPT common mistakes:
Starting work before CPT is approved on the I-20
Doing CPT not related to your major
Not following the approved dates on the I-20
D) OPT (Optional Practical Training)
OPT is work authorization that allows F-1 students to work in a job related to their major.
Key OPT facts:
OPT is usually up to 12 months per education level
You must apply to USCIS and receive approval (EAD card)
Work must be related to your field of study
Timing and deadlines are critical
Types of OPT:
Pre-Completion OPT (before graduating)
Post-Completion OPT (after graduating)
Timeline basics (general guidance):
Many students apply before program completion to avoid delays
There is a limited grace period after program end—missing deadlines can cause problems
Always confirm dates with your DSO and USCIS guidance.
Unemployment limit concept:
During post-completion OPT, there is an unemployment limit. Students must track this carefully.
OPT common mistakes:
Applying too late
Choosing wrong dates
Working in unrelated roles
Not reporting employment updates as required by school/SEVIS process
E) STEM OPT Extension (24 Months)
If your degree is in a STEM-designated field, you may qualify for a STEM OPT extension.
STEM OPT basics:
Adds up to 24 more months after regular OPT
Employer usually must be in E-Verify
Requires a training plan (commonly Form I-983)
Reporting and compliance requirements are stricter than normal OPT
Common STEM OPT mistakes:
Employer not eligible
Missing reporting deadlines
Not keeping training plan updated when job changes
F) SEVIS Transfer (Changing Schools Correctly)
A SEVIS transfer is when your SEVIS record moves from one SEVP school to another.
Common transfer situations:
Community college → University
University change before starting
New program at a different school
Key idea:
Your current school releases your SEVIS record on a chosen transfer release date, and the new school takes over and issues a new I-20.
Timing matters:
Missing transfer timelines can force a student into reinstatement or new SEVIS record. This is why you should plan early.
G) I-20 Deep Explanation (What Each Part Means)
Your I-20 is your main student document. You should understand these key parts:
1) Program Start Date
When your program begins. You can typically enter the U.S. only within an allowed window before this date.
2) Program End Date
Your expected completion date. If you need more time, you may need an extension before it ends.
3) Major / Program Information
Must match what you actually study.
4) Cost of Attendance
Estimated tuition + living expenses. This influences financial documents.
5) Funding Information
Shows how your study is funded (self, sponsor, scholarship, etc.).
6) SEVIS ID
Your unique ID used for SEVIS fee and tracking.
7) Travel Signature
If you travel outside the U.S., you may need a valid travel signature to return.
I-20 common mistakes:
Wrong name or date of birth
Wrong major
Incorrect funding
Not extending before program end date
H) Assistantships (RA / TA / GA)
Graduate students may have assistantship options that reduce tuition and provide a stipend.
Types:
RA (Research Assistant): research support under a professor
TA (Teaching Assistant): teaching support like labs or grading
GA (Graduate Assistant): administrative or department support
Important notes:
Availability depends on department and funding
Some roles start after the first term
Work hours must still follow F-1 rules
I) After Graduation Options (Common Paths)
After completing your program, common options include:
Post-completion OPT
STEM OPT (if eligible)
Transfer to a higher program (new I-20)
Return home and use the degree for career growth
Other work visa pathways may exist depending on employer and eligibility (general guidance only)
J) Common Mistakes Students Should Avoid
Working off-campus without authorization
Starting CPT before it’s printed/approved on I-20
Waiting too late for OPT application planning
Wrong dates or mismatched details across I-20 and forms
Ignoring DSO instructions or missing reporting deadlines
Relying on random social media advice instead of official guidance
