Yeah, seems a bit far-fetched, but I can imagine this happening with Indians going to work on manual labour jobs in gulf countries for example.
From my personal experience, the Immigration officer at New Delhi airport gave me a hard time when I first went abroad for studies cuz he could see that I was travelling for the first time. That was years ago, havent had any trouble since. But still, each time I am back there, I get the feeling that I have to keep my guard up. If not, somebody will try to
rip me off!
