I'm under J1 (au pair program), which I beleive that I'm not subject for 2 years HRR although it said in my passport that I am. I sent a request to have advisory opinion on Feb 24. Through this forum, I see some people mentioned that they can check the status online. Can anyone tell me how to do that? I call DOS yesterday and they said that they haven't had any info about my request. When should I expect to get the case number so that I can check the status online? Do they mail that out for us?
