Nicaraguan's entering Africa
I'm planning a trip to Mozambique next year and I have 2 friends from Nicaragua that I'm wanting to take along. I've heard from some people that there are countries they can't travel to being that they're not from the US. How do I find out the specific restrictions to the countries they can fly through and visit? Also I need information on how long they can be in Mozambique on a given visa? Would this be the same as with my US passport?
