As others have indicated, extradition is a creature of treaty. Most extradition treaties require double criminality. [International Criminal Law - Ilias Bantekas, Susan Nash - Google Books](http://books.google.com/books?id=q_SLzKU81QwC&pg=RA1-PA181&lpg=RA1-PA181&dq=extradition+double+criminality&source=web&ots=nL7YWEnmOl&sig=nmzZYXGIHDm5GA8wdyMOVr3NXGg&hl=en&sa=X&oi=book_result&resnum=7&ct=result)

So extradition and criminal jurisdiction are not coterminous.

To the OP: It’s important to distinguish between these two criminal concepts and the broader concept of civil personal jurisdiction. Plenty of foreign nationals get sued in the U.S. for a variety of activities. Whether they are subject to personal jurisdiction depends on a series of factors.

See, e.g., [http://www.uniset.ca/other/css/877FSupp1.html](http://www.uniset.ca/other/css/877FSupp1.html) for an example of a court refusing to enforce such a judgment on public policy grounds.

Actually, it’s a bit more complicated than that. See, [http://boards.straightdope.com/sdmb/showpost.php?p=7941823&postcount=9](http://boards.straightdope.com/sdmb/showpost.php?p=7941823&postcount=9)
