Becoming expat and living in Jakarta

Hi guys,

I am Felix from Berlin/Germany and 43 years old. I am married with my wife and her 3 kids from Jakarta. Still I live in Berlin, but want to move over to Jakarta and work and live there together with my family.
Here in Berlin I am working at the airport at check-in and boarding including passenger service. But i am open for any kind of job of course. The problem is, how start moving over to Jakarta and finding a job. To life there legal, I know I need to have a legal job and so on but how to find that and to manage all this..
Maybe some of you have good advices or any other help, like information and so on, I really would appreciate it! :-D

Kind regards, Felix
