Note: I have increased the specifity of this question, as well as adding information which was not available when it was first asked.
My partner and I would like to move to mainland Europe together.
I am a UK citizen, still living in the UK. My partner is an Iranian citizen, still living in Iran.
We have met in person, but have (of course) never lived together and the only evidence of our relationship would be our conversations on social media and travel receipts, to show that we have visited the same place at the same time.
I know that it is likely we would be expected to prove our relationship, though I haven't been able to find any guidance on what this would entail under our circumstances.
We are considering a move to Germany or Norway, primarily, though we have also discussed Sweden and Italy.
My partner had a meeting with a lawyer yesterday, where she was advised that the easiest option would be for her to move to Hungary or Italy independently (where she has the highest chance of being granted a visa), then we would be able to relocate together to our desired location within Europe.
At the moment, it looks like Germany is the most likely option. This is mainly because we both have friends there, though I have also read that expatriates who move before the 29th of March this year (the date of brexit) will retain their status and will face no difficulty in remaining in Germany. Although I do not live there currently, I would be able to relocate with relative ease.
I am unsure, though, whether the same rules would apply if I am already living in an area before my partner moves there, or whether we would both need to relocate to a new area.
If the former, then I can continue my plan to move to Germany prior to brexit and my partner will come to live with me as soon after she has moved to Hungary as possible.
However, if the latter is true, then I would have to wait until after brexit and reconsider my options based upon whatever legislation arises from it.
I have read that the freedom of movement directive is only guaranteed where both parties are moving to a new location, though I'm not sure if I've just misinterpreted this.
Based upon the above information, can anyone advise the most direct/hassle-free way to ensure that we are both able to reside together in Germany, or another EU country?
