You must be enrolled as a full-time student to be in F-1 status. If you complete your degree requirements at the end of a fall semester, you are not eligible to enroll in the spring semester. For this reason, international Yale College students in F-1 status who complete their degree requirements at the end of a fall semester will have an I-20 (immigration document) with a program end date that corresponds to the last day of exams of that fall semester. If you intend to complete your degree requirements at the end of a fall semester and if your current I-20 end date does not correspond to the last day of exams in that fall semester, please contact your designated OISS adviser.
If you wish to remain in the U.S. and gain practical experience post-graduation beyond the fall semester, you should apply for Post-Completion Optional Practical Training (OPT). You can start working in the U.S. using OPT in the Spring semester preceding the completion of your degree requirements. More information about OPT can be found on the OISS website.
