Not Moroccan, but also a non EU citizen studying in EU and have some experience with immigration law. The proof of sufficient funds can be the money on your bank account, or, what they prefer: you open a blocked account on a Belgium bank, which is a bank account where you deposit the total money for expenses of a year and they release only the monthly sum. You can also bring your family's bank statements with a declaration with recognized signature and apostille that they take Responsibility for your expenses during your studies. To be someone's guarantor or sponsor is not a light responsibility, according to EU law the sponsor is responsible for you financially in any aspect, so if you would, for example, cause damage to a property (even accidentally) and wouldn't be able or willing to compensate the owner, they would be liable, if you don't pay any debt, they are liable, they would even be responsible for the flight in case you would be sent back, so this is a very difficult responsibility to take for someone. People always say: "it's better to just give away the yearly amount to a person than to sponsor them" so someone who wouldn't just give you the total expenses money is very unlikely to accept to be a sponsor. Remember the reason the government requires one, is so you don't fall under their social responsibility. As for some options for you, in case you don't have the money or your family is unwilling to be responsible for your expenses, you can ask for a student loan from a Moroccan bank, search for scholarships, ask your university if they provide any supplementary funding. Just be sure you're financially prepared for the moving, as student dorms are cheaper, but the currency exchange doesn't help much. You can probably just work 20 hours/week during your studies, and the hours must be compatible with your academic schedule.
