If you're seriously going to find and marry a lady, I suggest Italian, French or a national of Norway. These,
AFAIK, are the easiest for quick permanent residence or nationality (ie work rights in EU). By the way, the so-called EEA2 registration card is for common-law/long term partners or spouses of EU/EEA nationals, even living in other EEA country. Meaning you can sort paperwork having Spanish lady and living in the UK. Do your research online as no point detailing it here.
The problem may be the passport initially, even if you have right to work through EEA2, some companies may be biased due to 'unrestricted movement' or 'EU passport' stipulations.
All of this above is on top of the
theory and not ideal job market as mentioned already. Oh, and if you have PIC time on heavier airliners, you may be exempt from the formal ground school racket, but still having to sit exams and the CPL LST could be in your sim, something like that. Or ATPL directly, since you got multicrew time.
You'd have to live in Europe long enough to know the only reason the grass is green is due to too much bureacratic
and lots of rain (UK/Eire).
