Answer 1

It's no big deal.

All they need is a valid passport and are able to visit on a visitors permit for 90 days

Answer 2

He still needs to apply for Visa on his own at US Embassy in Columbia and get approved.

Answer 3

As long as he's only visiting (I think the maximum stay is 90 days in that case) he should only need a passport.
