OK, well then there will be no record of where you are staying, you will not be visiting an immigration office for any reason, so there is no way for them to fine you, and it is very unlikely that your girlfriend would be fined either. I would just leave it.
Great reply as always. I hope this clears everything up for those always pushing the wrong info and abusing other members to further push their wrong information. Better to wait for an Admin if you don't know what you are talking about.
Paul Burns I have checked a number of times with transferwise, and taking into considering their high fees, my general bank transfer to SCB was better every time, even with the slightly better exchange rate with TW. I think people don't properly check other avenues before using transferwise. I am yet to use them unless I get more at the other end.
