What happens if my RNI (non resident) / temporary BSN 4 months expires and I have a job, but still not a place to register?
Do they somehow block my BSN so my next earnings at my bank account are blocked too?

And did anyone had the situation to be in a flexible work that was not guaranteed that you could pay a monthly rent or not yet had all the savings for the rent contracts that ask for some months in advance? Could you solve it somehow? Are there any options I could apply to have more time to find something suitable before registering, or receiving a “help” to pay later with not so much more costs?
