Do i need to bring anything?
Your question in such a manner will only attract vague answers.
That is to bring your NRIC and supporting documents.
In whatever letter u might have received will sure have clear indications on what to do. Otherwise, who or what made u think u have to go down? The caller whom u conversed with did not advise u on the stuff to take note?
Pls be clear on your situation if u wan fellow forum users to advise u. U have to play your part then only ask for support, not for the convenience of asking without doing any homework. Otherwise there will be a "moderator" in this particular forum questioning u over every single things u said and could give u a final conclusion of something similar to "that depends on whether cmpb wants to grant ur deferment", and "nobody here is the cmpb officer", or "what we say here doesnt mean what cmpb will do".
A complete total standard answer that is just a meaningless contribution
