I've noticed the US government enjoys not telling people what they need to know.
When I moved from Georgia to Ohio, not anywhere on their website did the Ohio DMV state I need my social security card to get my new plates. They told me I needed a picture ID, proof of residence, and a secondary proof of ID which included items such as birth certificate and debit card. I took well over 12 pieces of approved ID with me, including 3 different picture IDs, only to have the lady declare I had to have my social security card. I told her this was not a requirement listed on the website. She didn't care and she was incredibly rude on top of it. (A DMV employee??? I know right!)
Took me two weeks to go order a replacement SSN card, then try to get my new plates. That's when they decided to mention I also needed a vehicle inspection (new since I had moved out of Ohio) to make sure the VINs match. Who the heck was going to steal a 1993 Toyota Carolla? Oh and they didn't do inspections at their office, I had to drive twenty miles east to another branch....... GRRRRR!
By the third time I went in, if that ungrateful wench hadn't given me my plate, she was going to be eating it!
