I need to create personas for users who are from other country. The end users are learners and authors of US based universities who use an online learning tool. Now, how can I get understanding the user’s behaviour, goals, attitudes and frustrations while using the learning(users are learners) and authoring(users are authors) tools. I am based in India. Can you guys please suggest me some UX tools/methodologies for capturing the above information? Suggestions would be appreciated 
thanks !
