My OPT expired on 06/24/2013. I am planning to apply for COS to H4 before end of the June. Would to be advisable if I plan to travel at India in Mid October'2013 assuming I would get H4 approval notice before October. (Normal Processing time 2.5 months)Just curious to know. If I travel for urgent situation while my COS is pending. Is this considered as a illegal?
