I'm leaving to Brazil in a couple weeks but I have a problem... My passport has random spots for stamps available. In total there are 7 boxes that can be stamped but they are not in order and the free spaces is all over the passport... I already have Brazil visa. There are a couple random free boxes in the beginning pages of the passport that can be stamped and there is one spot on the last page that can be stamped. Will they look at the last page and see that there is only one spot available to stamp and won't allow me to enter? Or are they fine stamping the available boxes in the beginning of the passport?

Thanks for all the advice!
