Hi Keith. I was living in Spain when we got married so the application was to the Spanish Embassy in Manila. My income/assets were part of the paperwork which we had to submit but the attitude of Spain was that my wife would be given a visa for settlement without any problems. Spain had signed an EU Directive that it is practically illegal to keep spouses separated. Its a pity that UK will not sign too. I believe Portugal did sign.
My wife cannot go to UK, or even Gibraltar to go shopping, unless we have made the application, in person, at the British Embassy in Madrid (500 km away). We had a friend living here (permanent Residencia) in Spain. She married a guy from UK and they had to go through the whole, long, drawn out process for her to get a fiancée visa for UK.
