I am a Belgian citizen in my twenties. Next year, I'm planning to move to Singapore for work (as a postdoctoral researcher), with a one-year contract, which could possibly be extended afterwards.
I'm wondering if I should change my legal address to Singapore or keep the address of my parents in Belgium (which I intend to visit twice a year, say).
What is the most customary in this case, and beneficial (e.g. tax-wise)?
