We are from Brazil, and my mom overstayed her tourist visa, for over 5 years (not smart, but it happened), but came back to Brazil without any deportation letter, no problems with the police - she came out of free will (this was over 6 years ago). She wants to visit a very close friend now, and we were wondering how that should be put on the visa application - if it even should be put. She has opened her own company, has money etc. What to do in this case? Will they deny the visa no matter what?
