You are eligible to pursue Diploma in hotel management which is almost same for now. After completing your Diploma, you can pursue Bachelor's degree if you want.

After BHM, you can directly get jobs in hotels, cruise, hospitals, airway or all around the world and you can even apply for govt. jobs.

Hope it helped.

I am afraid you might not get immediately as a fresher because you will be having a tough competition from the students who have graduated in the same filed form the Hotel Management institutions. Starting salaries in this field are not more than INR 2.50 Lakhs per annum. Thereafter it would depend upon your credibility with the employers and exhibition of your skills. So think twice before taking the plunge.

The scope of MBA in Hospitality is increasing at a fast rate. It is not very high in India as of now but is expected to gather momentum in the years to come. But you must do it form a reputed institute which has a record of good and immediate placement in reputed hotels.
