I recently got my H1 approval (COS from H4). When can I apply for SSN?

My H1b is effective from October 1 2013.

Do i have to wait till Oct 1 before I can apply for my SSN?

Yes, after Oct 1 and your current status needs to be H-1 when applying for SSN.

How do i know if my H1B petition was filed with COS or not? I just have case number approved which states “Your I129 petition has been approved”? What does it say in case of H1B with COS ?

Look at the approval notice i.e. 797A or 797B. If it has an I-94 attached to the bottom of it, then it has been approved w/ COS.

You can apply for SSN 10 Days in advance, on or after Sep 21. Thanks!

Ask Employer to send a Copy of the H1B, if it came with an I-94; your are under COS.

Did you apply for it 10 days in advance?
