Pros:
- can vote
- can get security clearance, potentially more income
- even long periods abroad do not bear the risk of loosing privilege
- can do jury duty
Cons:
- need to do jury duty
- need to declare income to IRS regardless of residency
- potentially be taxed by IRS
Any other cons I'm not aware of? I heard that getting rid of the US citizenship (e.g. for tax reasons) will make it hard to get a visa ever again.
