This is a barrier I also had to cross as someone who is involved in a lot of interviewing (software engineers). I used to always break the ice with things like "Where ya from?" or "How long have you lived NYC?". To me it was natural to ask that when first meeting someone.
But over time I realized it makes some people uncomfortable. For example, someone with a thick accent (English is their second language) might take "Where ya from" to mean, "I noticed your accent, where is it from?".
As innocent as my intentions may be, I now believe it's not appropriate to ask questions like that during an interview process or at any time in the work place. Talk about movies, the weather, programming languages. If someone volunteers that type of information by all means engage with them.
And as an interview icebreaker just say, "It's so nice to meet you, we're glad to have you here. Should we get started?". Another one I now use is, "So what do you think of our office? Did you see all the snacks?".
I prefer using the same language in interviews as we do in office. If the candidate gets offended, chances are, he would be offended on the first day on the job; better weed those out early.
Or should I fear death by a thousand micro-agressions?
How should the good people of Chennai act accordingly to the delicate situation they might put me in for asking too many where-are-you-from's?

Edit: Or it might just stop with "where-are-you-from" :) Which is even worse. Don't get me wrong, I'm not against small talk. And I understand how difficult it can be to think about all this when your sole intention is just to be friendly with another person or build some common ground. I've been scenarios where, after I've told people where I'm from, I've been asked if I've ever had sex (since it's common knowledge that pre-marital sex in India is frowned upon) and I've been in scenarios where people don't know how to take the conversation forward. But I've also been in conversations where the outcome has been a fantastic cultural conversation! My only point being, there's more of a chance that you get asked these questions when you're in a minority group and if you've had certain bad experiences, you might get your shackles on when that question gets repeatedly asked. Is that making any sense? I'm happy to be educated if I'm missing something or should be thinking about this differently.
I ask white males such questions, and have been asked such questions as a white male. In environments where a significant fraction of the people do not come from there, asking where you come from is a normal ice breaker and opening to get to know someone.
If I avoid such questions when someone happens to not be white, will I be accused of racism? Someone could interpret that as me not wanting to get to know non-white people.
