Document needed for re-entry on visitor visa

[jsu1000]

My father in law (age 67) as 10 years multiple entry visa. He has visited US once on this visa last year. He is planning to visit again now.

What kind of documentation he must carry apart from passport with valid visa and return ticket?

i don't think so multiple entry unexpired visa requires ,any other important document to reenter the USA,where as there is a sufficient time difference between the two entries,as you said he visited you last year,i know many in my family and friends who traveled multiple times without any specific document other than you mentioned .rare thing left is medical insurance.

Thanks Sidxy! He has been in India for more than a year now since last visit. I was thinking if I have to send any address proof, bank balance or invitation letter etc.
