B1/B2 visa for my parent after a 10 year visa expired

[brokenarrow]

I want to apply for another term of B1/B2 visa for my parent. They had a 10 year multiple entry visa that expired in Jan 2010. They have never overstayed or extended any stay. Do they need to go to Chennai to get the visa or can they get it thorugh mail?

You cannot apply for them, only they can apply for themselves.

They must apply in person. Given their history, it should be easy if they have proper documents as before.
