USCIS says: "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"(See § Sec. 214.2(f)(5)(iii)). I was eligible and intended to register for fall semester when my summer vacation began in May, 2013. I and my spouse filed I-130 and I-485 concurrently and got receipts in August. So I decide now not to enroll for fall 2013. Will I be considered out of status from begining of summer vacation to the time I got 485 receipts in August since I changed my intention and do not actually enroll for fall term? Will my school DSO terminate my record in SEVIS using reason "failure to enroll"( see SEVP about "F and M Student Record Termination Reasons In SEVIS)? Many thanks!
