After doing the first Kitas there is essentially no leg work if you made enough copies.
They always request the exact same documents each time with the additional letter saying you're still married when converting to Kitap. Tbh Kitas renewal was the easiest thing and took 3-4 days when not around a holiday.
I still don't quite understand why they still ask for the Affidavit from before we were married but it's still part of the paperwork.
The biggest benefit to me for it being online is that since the documents basically all stay the same except the SKTT and previous years Kitas, I can just keep them on my computer. And both of those are emailed from the office anyway.
Wife got the customer service from Ditjen to respond to her as well and the gave her a different answer:
"Untuk verifikasi permohonan alih status di Ditjen Imigrasi memakan waktu 3-5 hari kerja. Sebelum permohonan diteruskan ke Ditjen Imigrasi, permohonan akan diperiksa di Kantor Imigrasi yg menerbitkan ITAS.
Proses verifikasi dapat memakan waktu lebih lama jika dokumen persyaratan tidak sesuai atau tidak lengkap, sehingga permohonan harus ditunda (pending)."
Meaning I should have my Kitap either Friday or after the week long holiday
