normaly sponsors give NOC, to give you another chance to stay in this country and work again. I suggest you utilize this favour from sponsor and try to get another job and dont fight for the ticket , whihc is hardly lesss than 1000 US$. Now priority is yours -- if you start fighting for the ticket, the sponsor may give you the ticket cost , but he has every right to deny the NOC and send u back to home country.
what is your priority ?
