@Stephen ********
if in Buengkan, expect them to do a home visit the first and second year. At the home visit they will want to talk to a witness. It can be the village boss, a neighbor or similar. They will want copies of that persons ID card and house book too. They will take a few photos around the house, and have the witness sign some papers (declaring it's true that you are married etc.)
They will call in advance, and it's just a quick and friendly visit.
Following years they don't make the home visit. At least not if you are at the same address.
Other than that, if you have your papers in order, expect a very relaxed, stream lined service with no fuss.
