Hi apologies in advance if this has been answered before but after searching the forum i am still not clear on the requirements.

1 I am a British Citizen living in Spain
2. i am resident here with the correct ID card/paperwork etc
3. i am retired so do not work or pay into the system here
4 i have my own house here
5 My girlfriend is born and bred Russian
6 She has a responsible position as a language teacher at the university
7 she has in the past been granted visas to travel (for work purposes) to both the UK and USA.

My question is what is the best and easiest way for us to be able to meet (in one or the others countries)

i am getting conflicting info from various sources...including embassys (when they can be bothered to reply)

we are told you can or cannot do the following
invite her to Spain on a private visit
i have to apply to the Russian embassy in london in person for a visa
i can apply by post/online to the russian embassy in Madrid
she will have to be invited to spain by an official body
she does/does not have to prove income
and on etc

Many thanks in advance for any assistance you may be able to give in these maters
