Also, her status changing from H4 to EAD doesn't affect your status at all. See #5 from my earlier post to you.
In any case, you can take the H4 approval notice and get the SSN. The card will say "Cannot work without authorization" (or something like that). So when she starts working, she presents the SSN card and EAD to the employer. I assume the same will happen with an EAD card but perhaps someone else can provide that info.
Also, it would be amazing if the govt was that synced. The USCIS trip over themselves and the DOS and USCIS are not synced. Forget about the SSA.
