dear sangram 

courses like barch will only flourish in future but unfortunately the demand to supply ratio is very low in india due to recent increase in popularity of this course.

if you want to be in india itself try to be a good architect and try for government jobs since jobs in private sector are very limited.or try and get a job outside india somewhere in middle east ,you will get better chance to shine there.

GOOD LUCK!
