So here is my current status in the US. I am on STEM OPT valid until November 2012 (F1 VISA valid until June 2013). My H1B is in process and the kick off date is at the end of October 2012.
Now my company wants me to travel to London for a month or so. Would it be advisable to travel on STEM while the H1B is in process. Since H1B kicks off only in October 2012, I was wondering can I return back on my F1? I recently (April 2012) came back from India on my STEM but that was when H1B process did not start. I am worried about the i94 arrival record changes and will that affect the H1B process.
