I do not know about RYR and "EU passport" required...
For me "Belgium/EU minded" - it means having the right to work in EU.
But it very well might be their requirements, but I would check on that.
And there are many other airlines you can apply with.
Like many mention it above, EU employment situation is bleak right now.
So do not leave your current job, but go ahead with your EU paperwork.
