Hi Pie...
I'm a Brit living in the Keys flying long haul for one of the 'big 3'...
My advice:
You have a MUCH better chance than most I've seen here in the last 13 yrs in making your dream come true, because you've married a local.
Get a plan together: she needs to work with the Embassy to start your sponsorship, yes you need financial support proof. You need an ATP.
The good news: timing excellent, we have very few pilots younger than you (FYI), 74% retire in next 15 yrs. That's about 6000 in our airline alone.
Put a definative plan together and work it through. I see no major roadblocks for you compared to many here.
Cheers
