I do a lot of programming, which is generally easiest with the US layout (since most languages were designed using this) but I also type frequently in a couple other languages which have extra characters. For me it’s easier to use than switching layouts.

Everyone knows that Albania actually rules the world

I can’t live without the EurKey layout! Even had to get approval to add it to our systems at one megacorp I worked for.

Not to mention, anyone who has worked in the US gets a SSN, not just citizens or current residents.

I know a bunch of people over here in europe who have them after working a few months/ years in the US.
