A little different but I travelled with my cat to the UK with him in the cabin (I bought him the seat next to me on Etihad). We actually had to fly to Amsterdam and then take the ferry to Hull, as you can't fly cats into the UK via cabin only cargo. Might be the same in Ireland. So best option is to fly to the EU then see if you could take a ferry maybe.
I have a feeling there wasn't a TM30 filed, because I was trying to get my vaccination but I spoke to the lady that did my visa for me and she said to register my address first. I assumed this would have been done with the visa, but I guess not
hmm my address has changed, so I will ask my landlord if he has filed the TM30. If he hasn't, do you know if I can just ask him to complete it and then take that with me too?
