So at some point you arrive in Amsterdam, be it in late August or late January, ready to do the school thing. Eventually you make it past all the initial issues: housing, class schedule, residence permit, bike, grocery store, and local pub. The essentials.
But often you'll start thinking, "dam I'm poor, and I've got time on my hands. I want to join the workforce!"
Now what are the options, one might wonder?
Well, the average administrative type at university will tell you "its complicated". They love closing doors in your face.
However, I've lived it. and complicated or not, even with all the so-called rules about how many hours an American student can work, I'd guesstimate about 50% of American students get part-time jobs over here. Most of those might be under-the-table. But a job is a job - right?
One thing you can work out, and its the best place to start, doing side work for your professors. Filing stuff. Writing stuff. Correcting stuff. All kinds of stuff. When I first arrived I found myself staring at a TV screen every afternoon, watching TV news and answering questions about it. Might sound boring to some, but all I heard was the sound of money landing in my pocket.
Which reminds me of a very common demand here in the Netherlands at Universities. Paper editing. While the scholarly types might use English for everything, most are not native speakers, and even the very fluent Dutch seek out native English speakers to correct their papers on underwater basketweaving in antarctica. Again.. it's money, and as a bonus, you learn new things.
I'll mention one more for today, and that is the job that you can always get all over the world for under-the-table money: bar and restaurant business. Although many eventually quit out of frustration and exhaustion, Amsterdam has plenty of bars and restaurants in need of young suckers like us, who need money and have the nerve to deal with drunken tourists. Irish pubs, I've noticed, are legendary for how fast students quit.

There you have it, useful tidbits on how to raise some Euros in between classes and parties.
