My question is this when does the year start again. My example I arrived in Brazil first time June 2016 stayed under 90 days a second time in October 4, 2016 I left in January 4. 2017 I overstayed one day just missed timed it. I want to go back for at least 6 months when does my year start to be able to be there for 6 months. Is it June, October or January. Thanks still trying to figure it out. I was told when I left could return in May but look like would only be for 3 months under what you are saying.
