I entered the US with AP in December, 2007. After that, in June, 2008, my employer applied for the extension of my H1B and it was approved in September, 2008. This extended H1B is valid until July, 2011. So, my understanding is that I was at the parolee status from December, 2007 to September, 2008, and after the approval of my extended H1B in september, 2008, my visa status was changed back to H1B. Is this right? Thank you very much for your response.
