I have a question: can a foreign company invest (buy real estate or commerce) in Peru without partnership / ownership of a peruvian company? Many countries limit possibilities of foreign companies, e.g. in Brazil it is not possible without opening a brazilian "branch" of your company...
how is the situation in Peru? Anyone knows?
Yes. You have to apply to a independent investor visa to run a company in Peru. http://www.expatperu.com/vrequirements.php#IIJ
