U.S. Social Security Administration

Approximate throughput of this office is 10 persons per 25 minutes. The best way to save time is to come 15 before opening. The personnel is quite friendly, all windows are open (there're about 8 windows or more). When you apply for an social security number the ss-5 form is not demanded, the officer is very likely just to ask you orally. Moreover, there are many chairs in the waiting hall, so it's pretty comfortable to await for your turn.
