My wife and son are visiting India and needs their H4 visa stamped. My current H1B petition is valid till Sept 2019 and so is theirs. My employer has filed H1B amendment since there is a project change and it is in progress. In DS160, I have mentioned the new H1B amendment receipt number. In my wife's ustraveldocs profile page, she has her approved H4 petition mentioned(Valid till Spt 2019). I hope all is good enough correct?She will be carrying her and my sons approved 1797, copy of my approved i797, copy of my amedment receipt number, marraige cert, birth cert, employee verification from my employer.
