Hello and thank you for using our service. My name isXXXXX and I am a licensed attorney and will try my best to help you. Believe me that I will try my best to give you a solution if one exists, but sometimes the law does not have a good one. Also, we have been having technical issues lately. If you respond and you do not see your response, please post again until you can see it because if you cannot see it, I cannot see it to respond.
You are asking if you will have any problems with the U.S. leaving the U.S.? Or if you need a visa to enter a specific South American country?
Well, I am asking because your question is in the U.S. law forum, not the forum for the laws of Peru. So you want to know if you will have an issue leaving the U.S. or an issue entering Peru?
