Calling visa and clearance house for Somali

Indonesians can sponsor a foreign national or a 60 day sosbud.
You may have to prove financial soundness as well as provide the usual documents.
Once married, if you intend to settle on Indonesia at some point, you can sponsor him for a KITAS.

Thankyou Fred for being helpful. We dont have plan to settle here. We also ready with our financial documents. I hope the calling visa process goes well, since I heard lot of people failed get it because of Somalia also one of restricted countries.

From memory, so check..

I understand Somali passport holders have to get an approval letter before they can apply for a visa and the maximum they can get is 30 days.
That, if memory serves, means you should get everything ready for the wedding as soon as his visa is granted (Fingers crossed for you) in order to make sure local wedding paperwork is sorted.
He would be best to bring his legalised birth certificate and any other documents he can think of with him, that including anything related to his Australian stay permits.
I've always found it's better to make sure everything is with you so you can provide anything at a moment's notice.
