You have to sit in exam to get licence from ICAN and you have to continue your COP from the organization where you have passed CA (i.e.CPA) exams. Exams is mandatory in Nepal though paper is less (not whole exams).

Since decade some of CPAs are working, is not yet get audit licence due to typical formalitites for CPA & ACCA. However, do not compare with ICAI members.

Thanks
