If you walk in, i suggest doing it first thing in the morning. You need a license, social security card, and a piece of mail with your current address dated within the last 30 days. Also, you will go through an exam, which the waiting time can be long, so expect to be 4 to 5 hours your first appointment, but after that it's just an hour visit.
Yu can jus walk in but yur first time is going to take anywhere between 3-5 hrs
