1500-2500 a month? That is a lot of hours of working on €10 hourly salary when combining it with studies. OP might be able to find something slightly better than €10, say €15 ph, but it will be a shit ton of work still and I would not make my budget/time allocation plans based on a higher salary than that.
Also, if you plan on going to a Dutch university, it will cost you €2200 a year. You’re lucky with that passport.
So about this; this tax benefit is going to disappear in a few years, if I am not mistaken the percentage of income exempt for taxes will in fact already decrease next year.
I assume we all have our opinions on that matter. But that does not change reality.
