My husband works in Belgium and has a work visa. I want to immigrate through Reunion. What should I do?

Belgium is not an immigrant country either. You can only do family reunion to accompany your husband, and you can only get it when your husband gets permanent residency. But if your husband can't get permanent residency, neither can you. This matter should be finished as soon as possible. Ask your husband to get all the materials ready over there, and then you can do all the notarization in China, and then you can apply for a visa at the embassy. It's estimated that it won't take long to get it, three months at most. It is best to get married for more than one year. If it is too short, I wonder if it will affect it.

In terms of materials, your husband should have proof of salary and income (at least in the last three months), then proof of housing (proof that there is enough living space for both of you), and then he may need proof of insurance or something. As for whether to apply to him, he'd better ask the Aliens Administration over there first. What is to be notarized here is mainly the notarization of your marriage relationship, your proof of no crime, and possibly your household registration certificate. You can ask your husband to go to the Aliens Administration over there and ask what the two sides need to prepare, and then you can ask the Belgian Embassy in China what else to prepare.
