I live in a non-US country, specifically speaking, i live in pakistan. Are there any country restrictions when it comes to working with amazon? can i start with amazon affiliate sites while in pakistan and target the US audience? if not, how do i counter this problem? should i use a vps, a proxy? or what should i learn in order to effectively hide my location and work as an affiliate? I do have a friend in america though, any tips on how to use him for this?
