The importance of nationality in employement

Thanks you for your answers. it’s true that exmar is a great company, but like all belgian company they’re going to hire belgian first, after europpean wich is normal. I’m really worried about that, i’am afraid to work hard get my licence, but don’t find a jobs after my studies, because moroccan fleet is ridiculous. Even if i really like this maritime world, i’m seriously thinking of changing orientation, i don’t wanna be disregard all my life, just because i don’t have a western passeport…so guys, based upon your experience you think passeport is that important in employement market in the merchant navy ? even with a good western licence ?
