Re: Hi, Im new today. Need some advise
You shouldn't need any of that.
When you arrive, go and register. You will need a work contract OR proof that you have enough money to live off OR maybe your girlfriend can sign to say she will support you.
You will also need your passport, passport photos, maybe a birth certificate (less than 6 months old), I was asked for proof that I wasn't paying tax in the UK anymore, which was a pain, but I don't think this is normal.
