Immigration did ask me why I wanted to get my KITAP when I just got my KITAS. They said you just paid Rp 2,000,000 why would I want to waste that money knowing I'd have to pay another Rp 5,000,000. I explained to them why do I want to go through the KITAS process again and again and only get 1 year permit to stay, when I can get (according to indonesian law) my 5 year KITAP. Ah I see they replied!
Yes this is just a basic VITAS, ITAS, KITAS, ITAP, KITAP conversion under the law but I'm attempting to complete it in just 10 weeks with no waiting after receiving my KITAS. Remember I applied for the KITAP the same day I got my KITAS.
