I have recently joined this forum and I was wondering if anyone could enlighten me as to how long the whole process takes from the time you write the exams (FPGEE) to being able to start working as an intern.
From some of the threads it seems as if a visa can only be applied for in April each year? Does this mean that even if you pass exams in June you would still need to wait till April the following year for the visa applications? Please can someone clarify the process for me. Thanks
