Question regarding travel

[aimmi]

Hello,
My inlaws have a 10 year multiple entry visa and have been to the USA only once before for about 2 months.This was 2 years ago. they are planning to visit again at the end of this year( December). My question is do they need any papers or letter from us that they are staying with us? at the port of entry? I think they dont need anything but just wanted to make sure. Do they have to have any documentation regarding purpose os stay etc? Any input will be appreciated

Thanks

They don't require any additional documents while coming again.

Before they come to USA, consider buying visitor medical insurance for them, available for instant purchase at https://www.insubuy.com
