Bless. Try to re-organize your petition letter/supporting documents and do this again -- there are many approvals with somewhat weak background. As long as you submit 140/485/AP/EAD application together and do not request PP, there is high chance that 140 is not adjudicated before EAD approval, and you can apply ssn with EAD safely then. Good luck!
Same here. The consulor told me I can transfer to F1, find a job in a compus, require for SSN, and then change back to H4 again. I am gonna try this way to save my husband's money and rescue my career. Hope it works to you too.
