Ones that insist on a "zip code"..even for non USA international visitors.
Some US forms try to be smarter, so when I am forced to put a 5-digit value for my 4-digit Aussie postcode, with a leading zero, it tells me there is no such ZIP code! US schools need to educate Americans that there are other countries out there.
I learnt the hard way (when I designed a multi-national form builder tool for an employer) that Hong Kong has no postal codes! I had to make that field optional. My education was also lacking. :)
I also learnt that a form for Taiwan might need six rows for the address!
While not a form issue, it does bug me that my cheap Nokia phone I use while in the US does not accept the plus as an international prefix and forces me to enter 011.
