H4 and EAD approval following concurrent application with spouse's H1B

Hey all! My spouse's H1B was recently approved and I want to know how long it usually takes for H4 and EAD to be approved afterwards.

What are your experiences?

Hopefully it comes soon! I'm waiting for an offer for a job and surely, this will be a factor for them if I'll get employed. My I-94 expires soon as well, unfortunately, so I'm not eligible for automatic extension.
