I called them, they said they could not check the mailing address for me. They said they might be able to provide the tracking number when I see the card was mailed to me. I have seen some people said that EAD does not have tracking number with USPS.
Hi Prakashkumar, SSN took 10 days. You need to go to the local SSN office to apply for it. If you have not got it in 2 weeks, you need to go there and check with them again.
