USA

Please contact the university for up-to-date fee information. The international student office will update you. Please note that living outside campus is more expensive.

I don't think options are available in US , you will find only MS or integrated Ph,D , graduate certificate courses are available in few universities but you need to hold an advanced degree for the same. If you are not interested in Masters there is no reason to prepare for GRE. Instead look for PG

Yes, you must take GRE and TOEFL. Also be aware that there is no government college. They are known as public or state universities. Other than these, they have private universities. You may also not find M.Tech. The degree notation is MS. Best of Luck.

Hi, an estimate - tuition fee is between Rs. 10-25 Lakhs a year and living expenses range between Rs.6 – 15 Lakhs.

Yes, you can. You will still need to apply for study permit and will apply as an Indian student that is as an international student. You may be exempted from giving TOEFL or IELTS if your BS is completed form an English speaking institution or country. Hope it helped. Best of Luck.

Apply for a job,simple! Visit job portals, check for requirements,an employer must sponsor your H1B visa for the same.

Dear Hemant, alongwith average colleges there are a few top universities too. Remember admission depends on the student's overall profile. Check University of Chicago Booth, UCLA, Babson College, Bentley, Boston University etc.
Best Wishes
