Strange to, on one level, make the valid and useful observation that forename + surname is a cultural assumption, then go right ahead and make the cultural assumption that the form should only accept US addresses (and even then ignoring DC, PR, Guam, and forces serving overseas...). Even with your scheme, you'd better hope nobody types in Beverly Hills, LA. And you'll need a spellchecker to help out people who can't spell Missississississippi.
