I apologize for not replying any sooner.
To learn the process of becoming an architect, review the full ARCHCareers.org website. In its simplest form, you need to pursue a professional NAAB accredited degree (www.naab.org). In addition, you will need to complete IDP - Intern Development Program (gaining experience) and take/pass the Architect Registration Examination.
That is the simple answer. Best.
