Dear student,
Firstly its really good to see that you want to study tourism further.
After 12th you have a lot of courses to do.
I would suggest that you do your UG from india only and go Abroad for the masters.
You can do BBA in tourism from NMIMS OR SYMBIOSIS.
You can also go for a specialised course in travel and tourism that would be also good.
You could go for B.A. as well.
All the best. I hope this was helpful to you.
