Don't know if this has already been posted. But Kantor Imigrasi South Jakarta has just moved from Lebak Bulus to its new building next to the Busway stop "Imigrasi" on Jalan Mampang Prapatan.
They moved about 2 weeks ago. Oh my god. It's got airconditioning that works, and the visa counter/photocopy room/payment counter are all next to each other (no more running up and down stairs).
