Mar 16 - Vosotros just in Spain?

Hi! I have a question about the pronoun, ''Vosotros''.

I know that in Spain they use Vosotros... what about in the other Spanish speaking countries such as Mexico, Guatemala, El Salvador, Honduras, and all the other Spanish Speaking countries?

I prefer the country Guatemala, because I will move down there in several years, and I need to know Spanish first, and I heard that they use, ''vos''? Is that the same as the ''vosotros'', since they both have the ''vos'' part?

Thanks!
