Their day-by-day itinerary doesn't have to show them out-and-about every day of their visit. Some days can be spent in, or even meeting relatives/friends/or doing nothing at all.Do prepare a day-by-day itinerary for sightseeing/meeting relatives and friends/activities with expense estimates + prove they can pay for it
I am not sure here why i have to say they will pay expenses as i am calling them and sponsoring and i am going to pay all expenses.?
That's the way it works for TRVs.
BTW the host does not *sponsor* someone for a TRV, s/he only invites a visitor.
You may eventually pay for all of their expenses, but to be approved for TRVs, they must prove they have little/no financial dependence on you = less likely to overstay their visit
