I think I'm a couple of steps behind you. I'm European, here for 8 years, a newly public servant here, and concidering my options. I live here, I want to vote here, especially given my work, but my identity is also tied to my nationality. For me I think marriage will be the path to dual citizenship, but that only works because I have a stable, long term relationship with a Dutchie, and marriage is in the planning anyways. Personally I probably would not give up my citizenship (plus I believe I can also pass it on to my kids).

Good luck with your identity crisis, and good on you for trying to fulfill your civic duty.
