India

Actually, it depends on your own budget. If your budget is more than 30 lakhs then I must suggest you go abroad. But if it is not the case then India is also a good option, not so much but it will do.

You have worked as a bank manager. It's a great thing and after seeing your profile I must suggest you that you have to take a chance with international business because nowadays in this field, such opportunities are available and amount of interested students in this field are really low. So, you have 90% chance to be successful in this field
And the answer to your question, it depends on your own budget. If your budget is more than 30 Lacs then I must suggest you that you go abroad.

The chances are 50-50. Fill counselling form of CET. You will come to know the college you are eligible for.

I have no idea about North India, but In Maharashtra, MIT College of Food Technology is a good option.

Dear Yogendra!
If you really want to do MBA in International Business or foreign trade then don't go for correspondence. Because these are some of the very core and critical thinking streams. Companies preference goes for those candidates who have done their full time MBA from a prestigious university. My advise will go for IIFT Delhi (Indian Institute of Foreign Trade Delhi). It's the best and specialised college for what you are dreaming for.
Good Luck.

Yes, it is a good option. You will get an edge over other candidates.
