F-1 Student Employment
Students maintaining F-1 status may work for Caltech a maximum of 20 hours per week while classes are in session and more than 20 hours per week during Institute breaks and holidays. Graduate stipends are considered on-campus employment. Caltech students whose employment location is at JPL are considered to be engaged in on-campus employment. On-campus employment is a benefit of F-1 status and does not require International Office approval.
CPT is an off-campus employment benefit available to students in F-1 status when the experience is considered to be an integral part of the established curriculum and directly related to the student's major. "Training" refers to a paid or unpaid internship, practicum, or other work experience that is required for the degree program, or for which course credit is awarded, or for institutionally sponsored cooperative education internships or research projects. Students are required to submit an application and receive an updated I-20 endorsed for CPT prior to beginning employment.
Please review and submit the CPT Recommendation Form at least three weeks prior to your anticipated employment start date.
CPT Application Process
- Obtain a letter from your prospective employer stating terms of employment, including: employment start and end end dates, full-time or part-time employment (part time is a maximum of 20 hours per week), and the address of your employer.
- Graduate students must submit the completed and signed CPT Recommendation Form along with a copy of your employment offer letter to the Graduate Office. A petition for sabbatical or detached duty is required. Non-academic positions may require a sabbatical. The Gradaute Office will then forward the approved forms to ISP to reveiw and create a new I-20 for the purpose of CPT. ISP will contact you once your new CPT I-20 is ready for pick up.
- Undergraduates submit the completed and signed CPT Recommendation Form along with a copy of your employment offer letter to ISP at least three weeks prior to anticipated start date. Please note: The form does require a Dean's signature.
OPT is an employment benefit that is available to students in F-1 status. OPT requires an application to, and authorization from, U.S. Citizenship and Immigration Services (USCIS) prior to beginning any employment. OPT applications may be received by USCIS a maximum of 90-days prior to completion of your academic program and must be received within 60-days after program completion. Graduate students may choose to use their defense date or the last date of the term in which they defend as the program completion date. Undergraduates will use the June commencement date as their program completion date. Undergraduate students completing in fall or winter quarter should contact their international advisor to determine the program completion date. Contact ISP to schedule an OPT application appointment.
