Somehow it is very fast for getting a EAD card from VSC, at least for my case and many other cases I saw in this forum.
My EAD will be expired in Nov this year. I applied in Aug. It took less than a month to get it. (paper application, not online). So I lost about 2 months.
Besides, if you don't get one after 90 days, you can get a interim card, right?
