Travel to Brazil

abstract_07 asked:


I was in Brazil last year and plan to go back in a few months, is my visa valid? Do I need to send off for another visa stamp?

They are an older couple (over 50), but have never traveled to the US, and are only middle class in Brazil. Does anyone have ideas of what I can do to help them acquire the visa?
Do you think sending them the invitation is enough proof that they have a valid reason to visit here?
Thanks for any help!
