CPT vs OPT: F-1 Work Authorization Compared
Compare CPT and OPT for F-1 students, including who authorizes each type of practical training, when it may be used, and what to confirm with your DSO.
The short answer
CPT is curriculum-based practical training authorized by your DSO for a particular opportunity before your program end date. OPT is training directly related to your major that requires a DSO recommendation and USCIS employment authorization. Which option may apply depends on your program, academic level, prior practical training, and individual circumstances.
Quick comparison
| CPT | OPT | |
|---|---|---|
| What it is | Curricular Practical Training is training that must be an integral part of an established curriculum and takes place before the program end date. | Optional Practical Training is employment or training directly related to your major area of study and may be authorized before or after program completion. |
| Eligibility | Generally requires one full academic year of full-time enrollment, although federal rules include a graduate-program exception when immediate CPT is required. Your DSO must confirm the curricular requirement. | Generally requires one full academic year of full-time enrollment. Your DSO recommends OPT, and USCIS decides the Form I-765 application. |
| Timing | Your DSO authorizes specific dates before the work begins. CPT may be part-time or full-time and must occur before the program end date. | The filing window depends on pre-completion, post-completion, or STEM OPT. You may not begin OPT until USCIS has authorized it and the start date on the EAD has arrived. |
| Employer requirements | CPT authorization is connected to a specific practical-training opportunity that satisfies your school's curricular requirements. | A job offer is not required to start the standard OPT approval process, but any OPT employment must be directly related to your major. STEM OPT has additional employer requirements. |
| Authorization source | Your DSO authorizes CPT in SEVIS and on Form I-20. CPT does not require a separate USCIS employment-authorization application. | Your DSO recommends OPT in SEVIS and on Form I-20; USCIS authorizes it through Form I-765 and an EAD. |
| Impact on later benefits | One year or more of full-time CPT makes a student ineligible for post-completion OPT at the same educational level. Part-time CPT does not have that consequence. | Up to 12 months may be authorized at an educational level. Pre-completion OPT reduces the post-completion OPT time available at that same level. |
How to evaluate the two paths
CPT is not simply an alternative filing choice: the opportunity must satisfy your school's curricular requirements, and the DSO must authorize it before employment begins. Standard OPT may offer more employer flexibility, but the work must remain directly related to your major and USCIS must authorize it.
Ask your DSO how your school applies CPT rules and how any prior CPT or OPT affects your current request. For eligibility questions or unusual employment arrangements, consider qualified immigration counsel. MyF1Status can help you organize the dates and preparation items you identify; it does not decide which authorization you qualify for.
