An F-1 student is expected to safe keep the initial I-20 ID bearing the admission number and any subsequent copies which have been issued to him or her. Should the student lose his or her current I-20 ID, a replacement copy bearing the same information as the lost copy, including any endorsement for employment and notations, may be issued by the designated school official (DSO).
The spouse and minor children accompanying an F-1 student are eligible for admission in F-2 status if the student is admitted in F-1 status. The spouse and minor children following-to-join an F-1 student are eligible for admission to the United States in F -2 status if they are able to demonstrate that the F-1 student has been admitted and is, or will be within 30 days, enrolled in a full course of study, or engaged in approved practical training following completion of studies. In either case, at the time they seek admission, the eligible spouse and minor children of an F-1 student with a SEVIS Form I-20 must individually present an original SEVIS Form I-20 issued in the name of each F-2 dependent issued by a school authorized by the Service for attendance by F-1 foreign students.

Except for border commuter students covered by the provisions of paragraph (f)(18) of this section, an F-1 student is admitted for duration of status. Duration of status is defined as the time during which an F-1 student is pursuing a full course of study at an educational institution approved by the Service for attendance by foreign students, or engaging in authorized practical training following completion of studies, except that an F-1 student who is admitted to attend a public high school is restricted to an aggregate of 12 months of study at any public high school(s). An F-1 student may be admitted for a period up to 30 days before the indicated report date or program start date listed on Form I-20. The student is considered to be maintaining status if he or she is making normal progress toward completing a course of study.
An F-1 student who continues from one educational level to another is considered to be maintaining status, provided that the transition to the new educational level is accomplished according to the transfer procedures.
An F-1 student at an academic institution is considered to be in status during the annual (or summer) vacation if the student is eligible and intends to register for the next term. A student attending a school on a quarter or trimester calendar who takes only one vacation a year during any one of the quarters or trimesters instead of during the summer is considered to be in status during that vacation, if the student has completed the equivalent of an academic year prior to taking the vacation.
An F-1 student who has completed a course of study and any authorized practical training following completion of studies will be allowed an additional 60-day period to prepare for departure from the United States or to transfer. An F-1 student authorized by the DSO to withdraw from classes will be allowed a 15-day period for departure from the United States. However, an F-1 student who fails to maintain a full course of study without the approval of the DSO or otherwise fails to maintain status is not eligible for an additional period for departure.
