Can I apply for a permanent residence card in Belgium for my retired parents?

The son lives in Belgium and his parents can emigrate.

Belgian immigrants can apply for one person and immigrate to the whole family. Belgium is the only country that can earn stable income among countries that invest in immigration.

Belgium has clear legal provisions. Foreigners can apply for a permanent residence card after legally residing in Belgium for five years, and the investment form is the fastest for three years. If they get a permanent residence card, they can apply for nationality. The key is that there is no language requirement.
