May I ask your help to understanding about architect's definition and criteria? Because of there are some confusing come up to me.
Actually I am not an architect, I have checked dictionary and other sites too. At the moment, I am in the final check process.
Therefore, I require your professional knowledge.

What is different between AIA & SARA?
And What is "Architect" definition and condition(criteria)of become an architect in USA and other countries?
Is it very important to have a Architect licence?
Some architects are not have a license, it means that does the architect is not architect?

Thank you for your help
