Last reviewed September 2026
Overview: F-1 is for academic institutions, M-1 for vocational and non-academic training. M-1 carries far more restrictive employment authorization and a different post-completion practical training structure than F-1's OPT. Both are now admitted for a fixed period rather than duration of status, following the DHS rule that took effect September 15, 2026, so the mechanics of tracking and extending status are converging even as the underlying employment rights stay very different.
Institution and program type
F-1 requires enrollment at a school certified by SEVP for academic programs; M-1 requires enrollment at a vocational or non-academic institution, such as a technical or trade school. A program's SEVP certification category, not the school's name or marketing, determines which visa applies.
Employment authorization during the program
F-1 students can use Curricular Practical Training (CPT) tied to the curriculum and Optional Practical Training (OPT) before or after completion. M-1 students have much narrower options: generally no CPT-equivalent during the program, and only a limited period of practical training after completing the course of study, tied to time already spent in the program rather than an open OPT-style benefit.
Fixed admission periods now apply to both
Under the rule that ended "duration of status" for F and J nonimmigrants effective September 15, 2026, F-1 students are now admitted only until the program end date on their Form I-20, capped at four years, with a 30-day arrival and 30-day departure period. M-1 students have long been subject to a comparable fixed-period structure, generally capped at one year or the length of the program, so this rule brings F-1's admission mechanics closer to what M-1 already required, rather than changing M-1 itself. Anyone needing more time on either visa beyond the authorized period generally has to file a formal extension of stay with USCIS rather than simply continuing to meet program requirements.
Practical training after completion
F-1's OPT allows up to 12 months of employment tied to the field of study, extendable by 24 months for qualifying STEM graduates, for a possible 36 months total. M-1's post-completion practical training is capped at a maximum of six months and requires the student to have accrued enough time in status to support that period; it does not have an equivalent to the STEM OPT extension.
Changing status between F-1 and M-1
A change of status between the two is possible, but the type of institution and program still has to genuinely support the new category; simply relabeling the same enrollment does not convert an academic program into a vocational one or vice versa. The rule that took effect in September 2026 also restricts starting a new academic program at the same or a lower level after completing one, which is a separate consideration from an F-1/M-1 switch but worth checking before assuming a transfer or new enrollment is straightforward.
Dependent rules
F-2 dependents of F-1 students and M-2 dependents of M-1 students are both barred from employment, and neither can generally engage in full-time study on the dependent visa itself; both are governed by the same fixed-admission-period framework as the principal visa holder.
Choosing the right visa when a program offer arrives
The institution decides this more than the student does: a program certified as vocational or non-academic under SEVP will issue an M-1 I-20, and an academic program will issue an F-1 I-20. The practical question worth asking before accepting an offer is how much post-completion employment time the program actually supports, since that gap between F-1's up to 36 months and M-1's six months is often the deciding factor for anyone weighing similar programs at different types of institutions.
