B2 - siblings travel for tourism

[SMT17]

Good day,

My 2 siblings and I want to travel to US for tourism next month. We are all adults each one has filled D 160 form and added the others as travel companions in his application [is it the right thing to do? ] .

Now for payment, should everyone pay for his visa and schedule appointment separately not mentioning travel companion?
or as a dependent?


Thanks

1. Yes.
2. Separately.
