after completing b.tech i want to change my line to Hotel managment espacially any cooking course 1 to 2 year. is it there any possiblity.

Yes there is possibility to do so. Its not exactly cooking but i would like to suggest you an alternate way. Why don't you go for a management degree (MBA) in hospitality and Hotel Management. from reputed colleges like MU, Manipal,Lovely Professional University etc. You would be boss at the place
