Never pay for your own rating,especially to fly for an unscrupulous bunch like this.LCA's in Europe have an incredibly bad reputation,unlike the American counterparts.
If someone tells you they're there and like it,they're probably either Belgian or Dutch with 300 hours,or Serbian and happy to be just flying,or Irish and in with the in-crowd at the white house,or just plain liars.
And no the FAA ticket wont do you any good anyhow,despite being a far more demanding exam.The 4 hour oral you will sit for any FAA commercial type means you must know the systems inside out.There's no A,B or C for you to guess....
