As long as the student remains in the U.S., it does not matter if the visa has expired because it is a travel document. All new international students at MCO participate in a mandatory orientation program during the first month of the unset of classes. Have an unexpired valid I-20, maintain a valid passport at least six months from the expiration date. There are valid exceptions to this rule, and students must contact OIS for the specific regulations. The INS makes the assumption that F-1 students are here for the primary purpose of attending schools.
Employment is restricted.
On-campus work is limited to 20 hours per week while school is in session and full time during school holidays. Dependent spouses of F-1 students may not legally work under any circumstances.
