Reason for Visit -

[skhelpim]

Very confused with this :

It is mentioned on this site that "Tourism" may be the right answer or the best answer for "Why do you want to go question ?"

I am just worried that this may be too vague a reply !

They are coming here to visit us and we are travelling to various places in NEast.

Any suggestions for other people as to what they have undergone .

Why do you want to go? Tourism.
And then of course, visa applicant should know some basic details about where he is going to tour, what are worth seeing places and all that. You can get more information at https://www.immihelp.com/usa-visas/visitor
