Hey bro.
Ksunandan, honestly i am not an immigration rules expert, i am obliged you ask me this, in my point of view principal applicant can land individually anytime before the expiry of visa, and with regards to family they can follow and join principal applicant anytime within validity of visa on PPT.
But there have been some blogs where others have mentioned family has gone first and then the principal applicant.
In my view i would like to ask my fellow senior members to answer this question and clear our doubts.
rgds,
hangza
