Yes you can. But along with writing CAT exam for being eligible for MBA, you'll also need to give GRE/ TOEFL/ IELTS examinations to pursue further studies in abroad. But if you are talking only about job, then yes you surely can apple for jobs abroad. Try to get into some of the best IIM colleges and work on your Group Discussion and Personal Interview rounds so that you crack the job offers for abroad.

Thank you.
