I have not any seat is not in dost why

It looks like you haven’t been allotted a seat in DOST yet. This could be because of your rank, the choices you selected, or the availability of seats in those colleges. Don’t worry, keep checking the official TS DOST website regularly. New phases and seat allotments are released, and you might get a seat in the next round. Also, make sure your options are wide enough to improve your chances!
