Hi there,
The aviation market in the US is always more fertile so it's always easier to get a job doing something in the piloting field even if that's not an airline job for the time being. In Europe, if you don't make it to the airlines within a few years, your options are more limited. If money is not an issue, I'd say get both sets of qualifications because it gives you the most scope and leverage. You can have plans but they can change so who knows where you'll be at in 5 or 10 years. If you think international certification and licensing is complicated now, wait until Brexit happens and get some popcorn.
