5. Do you have European citizenship or right to work in Europe?
If no, then it's pretty much pointless to aim for an EASA license. No EU airline / operator will hire you without having the legal right to live and work in the EU. Current job market situation in the EU is quite tight, career perspectives are much better in the US. If you're a US citizen I'd suggest get your FAA CPL/IR and your CFI afterwards and start building time. Once you've reached the hourly requirements (1500 hr) get your FAA ATP and I bet you'll be sitting in a jet cockpit faster than you think! If you're a determined and goal oriented person, this can be all achieved in as little as two years.
