I'm planning to go take my Extra Class test this month, one month after getting my General license. I know that Extra Class gets access to shorter callsigns, but I can't find any information on what is involved it getting assigned a callsign from that pool. Is it automatic with the upgrade, or do I need to request it? Secondly: If it does happen automatically, about how long does it take to happen from taking the test? The reason I'm asking is, I'm going to be licensing my new car around then, and if I get a new callsign, I want to use that for my plate instead of my current one.
