From what I have read in this Forum , at the KITAP issuance you receive also the "blue book" , then you have to deal with :
- The Manpower Department (for the final phase of the work permit/IMTA) ,
- The Regional Police/POLDA (for the SKLD which may require a new STM from local Police too) ,
- The Catatan Sipil/Kantor Kelurahan/Kantor Kecamatan/RT/RW (for KTP Orang Asing , Kartu Keluarga , other intermediary documents , ..?)
I suppose RPTKA and TA-01 are related to the initial phase of the work permit at Manpower Department , before you request the KITAP at immigration .
