I got F1 in Jan 2009. Got H1b approval in May 2009. H1b approval means just got I797B form. I preferred to join Fall 2009 semester in University and came in USA in Jul 2009, got I94 with F1 and continued to fulfill F1 obligations.Now I want to change my status from f1 to H1b, and its seems my employer needs to file a petition with form I-129, will that means it should be applied April 2010 and all the balloting process and I will be able to start work after 1st Oct 2010. Will my existing unused H1b approval be able to be used and to exempt cap and and all things required? And can I get I797
You are cap exempt and should be able to change status OR get H-1 visa stamping right away. No waiting till 1 Oct.
