Most of the Mesaba crews that I know would not take up that offer. They don't want to move from Minnesota, no place to ride snowmobile in Ireland.
There are too many jobs in the US for regional pilots. Soon to be shortage. Have a look on climbto350.com. Lots of jobs from corporate to float planes. Someday the US airlines will have to give out work permits just to find pilots. They already employ foreign cabin crew.
Also, why would someone in Europe want to fly in the US for $1800 a month (75 hours pm). Maybe you fancy the 8 sector days.
