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 Optional Practical Training (OPT)Temporary work authorization that lets eligible F-1 students work in a job directly related to their field of study. It can be used before or after completing a program, for up to 12 months in total at each education level, and students with certain STEM degrees can apply for a 24-month extension. USCIS grants it on Form I-765 after the school's designated school official recommends it.See it in the glossary. M-1 students are already admitted for a fixed period, and a 2026 DHS rule that would have done the same for F-1 students was blocked by a federal court on September 14, 2026, so F-1 remains on Duration of status (D/S)The period of stay for F, J and I nonimmigrants, who are admitted for as long as they maintain their program or activity rather than until a fixed date. It appears as D/S on Form I-94.See it in the glossary for now. 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)Work authorization for F-1 students for training that is an integral part of an established curriculum and directly related to their major. A designated school official authorizes it in SEVIS and on the Form I-20, and the student may start only after receiving the endorsed I-20. Students generally need one full academic year of enrollment first, and 12 months or more of full-time CPT makes a student ineligible for post-completion OPT at that education level.See it in the glossary (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: M-1 today, F-1 only if the rule takes effect
Under the DHS rule that would end duration of status for F and J nonimmigrants, F-1 students would be admitted only until the program end date on their Form I-20, capped at four years, with a 30-day departure period. A federal court blocked that rule on September 14, 2026, so it is not in effect. 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 the rule would bring F-1’s admission mechanics closer to what M-1 already requires rather than changing M-1 itself. An M-1 student needing more time beyond the authorized period generally has to file a formal extension of stay with USCIS.
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 statusMoving from one nonimmigrant category to another without leaving the United States, such as from B-2 visitor to F-1 student. It is requested from USCIS, usually on Form I-539 or Form I-129 depending on the category, and USCIS decides in its discretion. The request generally must be filed before the current authorized stay expires, and some categories, such as K-1, cannot change status. It is different from adjustment of status, which leads to permanent residence.See it in the glossary 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 blocked rule would also restrict starting a new academic program at the same or a lower level after completing one, a separate consideration from an F-1/M-1 switch that is worth checking if the rule takes effect.
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.
