This is pretty much a moot point. Getting an SSN is a very fast process. Anyway, in my case I started working (not on EAD but on TN), and got my SSN as soon as possible. Only problem is, no SSN no paycheck, so it is better for your spouse to get SSN as fast as possible.
Anyway, you don\'t need to wait for the SSN card to get in the mail, you can call them 2 or 3 days after you applied and they can give you the number by phone.
By the way, why are you multiposting this question, it makes your question look frivolous. Is your question serious, or are you just pulling our leg?
Good Luck!
