Need Information for Visitor Visa 10 years valid and visitng after 8 years

[my_colorado]

Hi
My mother in law is having 10 years visitor visa in 2002 , She visited US in 2002 and went back to india 2003. She is going to visit US next month. Do we need to send any kind of documentation for her upcoming visit?

Also in 2002 , I do not remember they took any finger prints/bio metric visa. So is there any thing now needs to be done now before the visit?

Any information is greatly appreciated

You might consider sending her an invitation letter so she can show it to a US immigration officer when entering the country.

Don't need any invitation letter, sponsor letter or any such documents.

Just need air tickets and visitors insurance.

No problem that no fingerprint was taken. It will be taken at the US airport.
