Money laundering is falsifying financial info to disguise the source of the money. People are allowed to give you money and you are allowed to take it, as long as you report accurately and pay taxes it’s fine. Where you might run into trouble is the school or people/orgs attached to the school giving you money on the condition of you going out staying there. Basically the money has to be donated without any agreements being made and it would be fine. As I understand things, I am not an expert or even particularly knowledgeable, but you ask strangers on the Internet and you get what you get 🤣
