then you must buy another one 30 months later.
With a Kiwi bird when I came to NZ. Makes you appreciate their immigration system when thinking back about the nightmares applying for a work visa for her for the UK. Our mob couldn't have been any more less helpful or rude if you paid them to. The hilarious thing was, her case officer could barely speak a word of English, yet tried to be rude. Told him on the phone that we need a translator and preferably one with a modicum of manners. He started piping up and I told him to shut up and learn to speak English and get some manners or bugger back on the banana ship he came in on. Let's just say it nearly reflected in the visa decision.
When I applied, it was awesome. Lovely Kiwi bloke, after my documentation was checked, I got a decision within 2 days giving me a year work visa. I could've applied for residency straight away but it takes like 9 months or something. I applied for it anyway right after my work visa and got a decision within 4 months. I can now live here forever. My residency case officer was awesome and we kept wise cracking on football results. He even mailed me 'LOL' after Arsenal lost against Tottenham. Imagine the sour pusses with chips on their shoulders at the UK Home Office doing that.
My wife is Welsh if that counts?
Yes, and to make it more fun we got married in a 3rd country. Really, where you get married makes very little difference, as long as you get a valid marriage certificate then any country will deem it necessary evidence. For certain visas you may need to provide supplimentary data such as proof of shared bank accounts, photos of you together on holiday, email discussions going back X years etc.
You can't registers your marriage in another country AFAIK, so if you are going to get married in the UK there is nothing you need to tell Portugal under normal circumstances.
