May I suggest that those foreign pilots have the right to work in the US, married to a US citizen or a green card perhaps?
Meanwhile, you won't be allowed to work in Europe (bearing in mind since the 1st of Jan Romania is now in Europe) without a work permit. And to fly in a JAR member state, you must have a JAA licence. Much like you have to have an FAA licence to work in the USA.
There seems to a shortage of qulified and experienced pilots in Europe right now. An I suspect since monday Romanian pilots are all applying for better paid jobs in Western Europe, so there may be jobs going thee. But if you have the right to work in Europe, why not chose to work where the pay is better?
