Thanks Ramjet for you detailed respond, it's helped a lot.
I'm a holder of SACAA CPL and don't have the SACAA ATPL! the question is with my SACAA CPL do I have to write a CPAER exam first before INRAT exam? and if my flight experiences are count toward the TC ATPL? my ATR type rating is issued P1 in my SACAA license and i have 500hrs PICUS but only 100hrs PIC in single engine! and if i write the TC exams my license would be based on my foreign license or it will be a clean license?
Thanks again,
Amin
