@Karnali: i goth the tps while i was on end period of OPT at the same time i was approved on h1b so now i am working on h1b from OCT 1.I am not touching TPS EAD until and unless there is emergency i mean if anything happen to h1b.So, I am just keeping TPS as for BAckup.And also planning to go to nepal for stamping by taking AP from TPS so if my h1b is not stamped also, i can come back through TPS AP.Hope it clears.Let me know if you need more doubt.

Regards,
Raja
