Found the
LASORS UK CAA reference.
Section G. G 1.5 pg 315.
Valid for United Kingdom registered aircraft. As this licence does not fully comply with JAR-FCL the holder must have permission from any other JAA member state prior to exercising the licence privileges in aircraft registered in that state.
This endorsement may be removed by obtaining a pass in all JAR-FCL ATPL(A) theoretical examinations.
So, it doesn't fully comply with the EU rules.
You need 3000 hours TT with 1500 hours in command, not 3000 hours in command of 30t (or 30,000kg - picky....
) in primarily international etc....
So, if the other member state says "yes" to your 2 exam UK CAA ATPL, off you go. If they say "no", then you'll have to get on with the additional 12 exams. Fun.
However, they do not have to recognise it as it doesn't comply with JAR-FCL.
I know at least one person who had a Dutch national licence converted to a Dutch JAR ATPL who then got a UK JAR ATPL. (They weren't happy but it was during the time when the national authorities were all changing to JAA and there was a lot of confusion)
Oh finally noticed the bit about not having a European passport.. Tricky. Unless you can get an ancestral visa, you're stuffed.
Sorry.
