You can. You can get the application from Indian embassy. But I guess you have to come to India to write it. My brother just took the exam.
But you dont need to take civil services for intelligence service job. Look for notifications in newspaper for jobs from cabinet secretariat. These are direct RAW, IB cadre jobs and come for interpreters and such pathetic names.
So you don;t need to take IPS exam to get involved with IB or RAW? IS there any way to find out the newspaper notifications....I mean that is not an effective way of finding candidates. I was just thinking israel routinely recruits from jews who are born abroad to serve. Plz any info would be kindly and greatly appreciated...
