But as per my search, I found that we have to have return ticket. because, they must take our final interview over there.
Its obvious that we will be selected but if we are disqualify at this stage then we have to return back.
Therefore we have to have return ticket as per their rule.
that you must have to know and be prepared for landing.
after granting VISA the POE officer will look your visa, medical papers , POF , B4 forms etc mandatory docs are there, if you fail to prove requested documents then the POE officer will return you back , otherwise no reason to return you back, once your all docs are well set.
so, becarefull that land before medical , visa or passport which one is latest expired, bring complete or more amount of requested POF, fill out B4 form nicely , keep handy all madatory documents, no one will return you back from POE if requested documents are clear and good enough.
