I am in H1, and my son's passport expiry was on 22-Aug-12, hence when he entered USA on 5th Nov 2011, his I94 was issued with validity until 22-Aug-12. Now I have the passport renewed, and wanted to apply i94 extension. when I was filling the efiling form in USCIS website, I am asked to provide Alien Registration Number or SSN. SInce he is 6yrs old, I dont have SSN / TIN, and not sure how to get Alien Registration Number. I would like to know if this is the correct process (efiling) and how do I get Alien Registration Number?
thanks for your help
