BHM

Congratulations on completing BHM. "Bright Future" is a very subjective issue and I need to know your areas of interest to answer it more convincingly. Still, I will give a general reply.
You should work for a couple of years and then if possible go abroad and do a specialised course at PG level to develop the expertise.
Hope this information helped you.

Normally, such brands don't take candidates without BHM degree but if you have exceptional abilities and skills, they may hire you at a very basic, entry level and then you can grow with your performances. To get that entry will not be easy. It will require lots of persuasions and chasing.
All the Best.

It is great to know your have completed your BHM. One of the best university for distance is IGNOU. You can fill the online forms and after that the procedures will be updated to you. Its easy and simple.

No. It's not possible and you need to start a new educational year.

If you have a 12th/+2 pass certificate, you can definitely apply for BHM wherever you wish to study.

Where in Nepal is more important? The bigger the city, the better the exposure and faculty quality. I can't give a generalized answer regarding whole of Nepal. If it is Kathmandu then it is better but if you compare Delhi with Kathmandu, any day Delhi will be better.

If you have not got through IHM, Chennai then you should definitely consider hotel management program offered by SRM University.
