didnt understand what yuou are saying amit. You said you h1b is approved. Then why do you need to extend your OPT. Since your h1b is approved and will take effect from Oct 1, you will be in status till october because of the new cap gap rule and you dont need to extend your opt.

Just curoius because my opt also expires on July and h1b will be effective from October.calirification will be highly appreciated.
