Day 1 Curricular Practical Training (CPT) is a work authorization option for F-1 international students that allows them to begin practical training related to their field of study from the very first day of their academic program. It is commonly used by working professionals who return to school while continuing employment. While Day 1 CPT offers flexibility, students must follow certain immigration guidelines—one of the most important being the 150-day rule. This rule is especially relevant when a student plans to transfer from one SEVP-certified school to another while on CPT.

The 150-day rule refers to the maximum allowed gap—150 calendar days—between the last date of attendance at a previous school and the start date at a new school. This rule helps ensure that a student maintains continuous F-1 status during the transfer process. If the gap exceeds 150 days, the student’s SEVIS record may be terminated, potentially resulting in loss of legal status and the need to depart the U.S. and re-enter with a new I-20.

Because Day 1 CPT students often transfer to different programs to continue working legally, understanding and following the 150-day rule is critical. The countdown includes weekends and holidays, so accurate planning is necessary. For instance, if a student finishes a semester on May 1st, the next program must begin before September 28th to comply with the rule.

In summary, the 150-day rule plays a key role in maintaining F-1 visa status during school transfers, especially for students on Day 1 CPT. It’s important to stay informed and plan accordingly to avoid falling out of status and facing immigration challenges.
