I volunteer with a foundation in Tanzania and one of our sponsors wants to bring one of the adult children to the USA for a vacation. She is an 18 ye old student and was already denied once. Hoping someone might have some pointers on what could help get her the approved the second time around. The sponsor is covering all of her travel expenses, providing room and board and all paid expenses while she is on the USA https://19216801.onl/https://routerlogin.uno/​ .
