Dear,
I am from India, currently working in Belgium with a single permit (Type B work permit loaded to Residence Permit). I am changing my employer, my current employment ends by 31-July, then I am planning to visit India and come back to Belgium and join my new employer on 26-Aug. But when I re-enter Belgium in August my residence permit will be valid but my work permit would have been deregistered by my current employer by that time. Would I be stopped at immigration if my residence permit is not attached to any work permit?
Note: My new employer is initiating a EU Blue card in which I will be having a temporary / provisional work permit with me in August, with which I can start working, but I will apply for a blue card which will take up to 90 days, during which my current residence permit is valid.
