here in qtr employer have full right to terminate employee any time, no matter you are anywhere.you should ready for it.here in your case it depend on your productvity and the need of your employer.I am sure if they need you they will not cancel you but they can do it.what you can do to demand noc now ,so if they cancell you can try other place. if they give you means they will call you back.
But my exprience say that they will not cancell you but you shouldbe ready for any situation.
