Consular access if arrested in a foreign country, I guess. A US embassy will try to make sure you have access to a lawyer and medical treatment, they're actually useful that way.
(Unlike, for example, Australia).
Of course, the downside is nonresident taxation. Like Eritrea and North Korea, the USA will keep taxing you even if you leave the country if you keep your US citizenship. And if you want to give up your US citizenship, there are exit taxes!
hurm. isnt consular access generally the same for all citizen?
I well remember reading about an Australian doctor who developed a new way to store blood products. Getting the permits to start such a business in Australia was far too expensive, so he moved to China to commercialise it. After a couple of years it was a huge business, so a PLAF colonel had the doctor thrown into a "black site" prison on fake charges and forced him to sign over the business.
Australia's government did nothing, except threaten the doctor's family that talking to the press about it would mean the doctor could never return home.
After two years they went public. Australia's government still did nothing.
I've never needed consular assistance overseas, but I did once need to visit an Australian Embassy to apply for citizenship-by-descent for my son. Even with an appointment, it took days.
USA is much, much better than that for its citizens abroad.
