Is Swiss citizenship hard to get?

The process for becoming a Swiss citizen varies between cantons but it is typically lengthy and usually takes several years. Securing Swiss citizenship can also be a costly process, as there are three levels of authorisation; therefore fees need to be paid at the federal, cantonal and commune levels.

Do they check train tickets in Switzerland?

Yes, the train system operates on the honour system in Switzerland. They expect people to pay for their tickets but will do random checks from time to time. Very rarely do I see anyone get caught and fined as most Swiss dont mind paying for a ticket.
