Rediff.com regrets to announce the death of Dr Arun Vakil on January 30.

Dr Vakil, a US visa expert, had been a regular contributor to Get Ahead and hosted a number of chats with our readers on studying in the US and visas issues.

Here are some of his articles and transcripts of chats he hosted:

• How and when to apply for H-1B visa to the US
• H-1B visa: 'Your employer must do all the paperwork'
