Also I've started a thread on Azmath at
Families shattered over arrest (Azmath illegal in US 9 years- John Doe2?)
That is a Times of India article that explains Azmath came to the US illegally 9 years ago. There are links at that thread to two other TOI articles on Azmath and I've posted the 4 pictures again too.
