I think he cannot be employed in Europe. He needs to be employed or self-employed in Morocco. What is he able to do? Maybe, I can hire him.
Please read the list of nomad visas yourself and decide which country is cheap enough yourself. Czechia would also be an option.
@gatrader with all due respect. But could you please at least read the stuff we send you? Non of us here is getting money from answering your questions. Please do your own research as well. We told you the way to go with the nomad visa and you keep telling us that you do not have a company in the EU. Have you even read what the nomad visa is? I highly doubt it. Please, we are here to help but we also expect the posters to spend at least the same amount of time thinking about it as it takes us to respond. And this is the same for once in Schengen. The place is full of lazy people that don't want to spend money, we not need more of them.
I'm not lazy; I've looked up a lot about this nomad visa online but still don't get exactly what to do or if he needs to have ties to Germany or other places to apply. It's sad to see people being mean when someone asks questions, too many lions behind a keyboard. I thought this place was for sharing info freely, so I don't get why you say I'm lazy or don't want to spend money.
