Hi,
I have a single permit with unlimited duration (onbepaalde duur) from Flanders, so it is not tied to a specific company. As far as I know, I should be able to change jobs like a Belgium citizen: resign, and after notice period, start to your new job. No need for additional paperwork.
Last week, an HR person from a company I applied told me that there is still some paperwork to hire me which may take two months. I am very surprised. I think she is not right. Can somebody confirm?
I couldn't find any official page for "change of employer procedure" specifically for single permit onbepaalde duur. Only info I find is for procedure for those with regular single permit ("beperkt", limited)
Thanks!
