@HonkHonkBoom @GoonPatrol @Momther @Shlomo It's unfortunately rather strict.
Ideally you need to find a job first, then you can usually get a permit to stay somewhat easily.
Alternatively, you can try to find a woman to marry, much like in the US, then you're legally in family and therefore can get to stay.
You say 'without significant job skills', but surely you have something you can do. Do you speak any unusual language, something non-English? Translation jobs are a thing.
