Hi Ilya
You'll have to provide income information, but I don't think you'll get rejected solely based on it. Even if you aren't employed during your studies, you can still take out student loans. If you really plan on working during your studies, I suggest having a look at this site: https://duo.nl/particulier/student-finance/. If you're an EU citizen and you work for at least 56 hours/month you'll be eligible for a grant of up to 400 euros/month.
