Officially, an SKTT is no longer required for an expatriate worker and his family members in Jakarta. However for expats and their families who live in other provinces, the SKTT/ Domicile Permits are still mandatory, for foreigners recently arriving in Indonesia. If you need this document in the town you are living in, the Human Resources department in the working spouse’s office should apply and obtain it for you.

While we know that the SKTT is not logner required for expats living in Jakarta, we also know that if you own a car in Indonesia, the SKTT or Domicile Letter will be required to renew documents and in the past you’ve needed it to get a drivers license and renew your car’s ownership documents. Confused, that’s what changing regulations causes. When in doubt, check with your company’s human resources department to be sure that they’ve obtained all the required documents for you!

Foreign Individuals who have obtained a work permit and an ITAS are considered residents, just as citizens are. As such, they must register with the local municipality’s population office (Kantor Catatan Sipil – or Civil Registry to obtain a Certificate of Registration for Temporary Resident (SKPPS).

SKTT – Surat Keterangan Tempat Tinggal A Certificate of Place of Residence must be obtained from the Sub-district Office (Kantor Kelurahan in your area.

SKPRK – Surat Keterangan Penelitian Registrasi Kependudukan

Applying for a SKPPS – Surat Keterangan Pendaftaran Penduduk Sementara (Certificate of Registration for Temporary Resident)

Resident foreigners need to go to their local Kantor Lurah to get a Surat Keterengan Domisili stating their address of residency in Indonesia. This letter is then brought to the Catatan Sipil (Divil Registry) in order to apply for a SKTT (Surat Keterangan Tempat Tinggal), a SKPPS (Surat Keterengan Pendaftaran PendudukSementara) and a SKDLN (Surat Keterengan Datang dari Luar Negeri). A foreigner residing in Indonesia on an ITAS MUST register at the Catatan Sipil to get these documents.

Having them in requed as well for an application for an ITAP later in your stay. Once the three documents are issued, the Catatan Sipil office may issue issue a green card which verifies your residency and registration as a temporary resident for the length of your ITAS . The fees are defined by local regulations and vary depending on each city/district. It shouldn’t cost more than Rp 150,000.

The SKPPS , along with the SKDLN (Surat keterengan datang dari Luar negeri) are just part of the process to apply for the SKTT. Only the SKTT is issued and given to you. The SKDLN and SKPPS usually remain at the Catatan Sipil office (they are forms that you fill to get the SKTT issued).

Here the list of all the documents requested for the application:

1) 3 pictures 4 x 6
2) Photocopy ITAS / Kitap
3) Photocopy Pasport
4) Surat pengantaran RT / RW
5) Photo copy Kartu Keluarga
6) Photo copy marriage certificate
7) Surat sponsor unt. SKPPS dari suami /istri
8) Surat permohonan unt. SKPPS dari suami / istri

Then I was asked to come back one week later to pick up the finished SKPPS at the loket outside, while being told that it will cost 100 000 Rupiah.
